In detail: do-it-yourself gas generator repair from a real master for the site my.housecope.com.
A portable electric generator is an irreplaceable source of energy in conditions when there is no possibility of connecting to electric mains or the supply of electricity through them is interrupted. They use ordinary motor gasoline as fuel.
A portable power generator will be useful wherever there is no permanent power source, for example, on a trip to nature.
Diesel power generators have a large mass, therefore, they are installed permanently as a backup source of electricity. Their gasoline counterpart is much lighter, therefore, it is quite mobile and is often taken with them to remote, inaccessible places. Therefore, in the event of a breakdown of a gas generator, it is extremely problematic to call a repair specialist; it becomes necessary to repair it yourself, with your own hands.
The device of a portable gasoline electric generator.
Such a machine is a mechanism for generating alternating current based on the synchronous rotation of its elements. Moreover, such a current, depending on its model and power, can be either single-phase or three-phase. The first has the ability to generate a voltage of 220 V and supply a single-phase load with current, which is necessary for electric lighting and the operation of most household electrical appliances. The second one can give a load in three phases and provide a voltage of 380 V, which makes it possible to connect, first of all, welding machines.
The gas generator consists of an electric generator and a gasoline engine that supplies it with energy. They are connected to each other by a special elastic coupling. A metal box is installed near the generator, where a device for turning it on, instruments for measuring operating parameters and automatic fuses in case of short circuits are mounted. The gasoline engine can have from 1 to 8 cylinders, depending on the required power, and also be two- or four-stroke. The latter are used more often, since they are more economical and have a higher efficiency. The method of switching on can be either from a spark obtained mechanically with the help of a manual drive, or from a battery.

The main reasons for failures in the operation of a portable gas generator can be either engine breakdown or failure of an electric generator. To find out the specific cause of the malfunction, you will have to check one by one all the nodes that can cause the failure.
Generator internal circuit diagram: 1. Fuel filters. 2. Crankshaft. 3. Air filter. 4. Part of the ignition system. 5. Cylinder. 6. Valve. 7. Crankshaft bearing.
In addition, the load on the generator may exceed its capacity. Then you need to turn it off and check the work. If, during the operation of the unit, smoke begins to rise from it and a burning smell appears, it means that a short circuit has occurred in the winding, then self-repair is extremely problematic, a complete rewinding of the windings is needed.
VIDEO In general, repairing a gas generator on your own is quite affordable even in the field.
Gasoline generators, even if they are made in China, very reliable with proper care ... Nevertheless, during their operation, small problems can arise that can usually be quickly fixed with your own hands. Serious breakdowns with the knowledge of the owner of the device and the principle of operation of the generator will also not be able to disable it for a long time.
If you arrange possible malfunctions of the gas generator in a kind of rating, you get the following list:
Failure or contamination of the spark plug: difficult or impossible starting, unstable operation.
Clogged carburetor: difficult starting, excessive fuel consumption, unstable operation under constant load.
Failure of the ignition coil: no spark, inability to start.
Starter breakdowns: breakage, biting of the cable, destruction of the ratchet.
Violation of valve clearances: difficult starting, increased noise during operation.
Wear of brushes (on synchronous generators) - lack of output voltage.
Speed governor malfunction: floating engine speed, dips when changing the load.
Wear of the bearings of the crankshaft and the rotor of the generator - an increase in operating noise, oil leakage.
Wear of the cylinder, piston rings - difficult starting of a cold engine, excessive oil consumption.
It does not take into account breakdowns that result from a gross violation of the rules for operating the generator: for example, seizures on the crankshaft neck due to insufficient oil level, burnout of the generator windings or voltage converter (on inverter gas generators) with frequent overloads.
In fact, malfunctions of a gasoline generator can be divided into three groups: mechanical, electrical and fuel / ignition system malfunctions .
Difficulty starting the generator, which manifested itself suddenly and not accompanied by an increase in engine noise, is a clear sign of either deviations in the operation of the carburetor (too lean or rich mixture), or a faulty ignition system (weak or intermittent spark formation). Since the diagnostics of the state of these systems is interconnected, it is combined into one section.
Remove the spark plug and inspect the carbon deposits on the electrodes.
Dense and dry black carbon deposits - a sign of a rich mixture (the carburetor is faulty, the air filter is clogged);Oily black carbon - a sign of severe wear of the piston rings, oil enters the combustion chamber;White soot - a sign of running on a lean mixture, it is necessary to check the carburetor.Brick brown carbon deposits - normal for carburetor engines.Red, green-red carbon deposits - a consequence of working on low-quality fuel.It is simple to check the performance of the ignition system itself because of its extreme simplicity: turn on the ignition, insert a known good spark plug into the plug cap and, putting it on the nearest metal part of the engine with its skirt, turn the recoil starter abruptly. If there is no spark, disconnect the ignition switch and the oil level sensor from the ignition coil in turn: if, when both elements are disconnected, there is still no spark, replace the ignition coil.
If the spark is present and strong enough (white or blue-white), remove the spark plug after several starting attempts. A candle filled with gasoline is a sign of an over-enrichment of the mixture, a dry one is a lack of fuel.
Sometimes, after long storage, the needle and the carburetor float stick and prevent gasoline from flowing inside. Several times sharply, but do not hit the float chamber lid very hard and start again.
The most common carburetor malfunction is contamination. The ingress of dirt into the air channels leads to an over-enrichment of the mixture, into the fuel jets - to a depletion. Dirt on the float shut-off needle leads to loss of tightness and overfilling of the float chamber, which will be immediately noticeable by the leakage of fuel from the carburetor.
Let's take a look at the carburetor maintenance on the example of a Honda GX engine - its design is typical for a gasoline generator.
Remove the float chamber cover (4). Wash it in gasoline or a carburetor spray cleaner - dirt and deposits accumulate on the bottom.
Proceed in the same way with the gas valve sump (22).
Check if the gas valve is blown in the "open" position.
Take out the float shaft (3), take out the float and the shut-off needle (2). Blow out the channel with air.
Blow out the fuel jet (25), emulsion tube (11) and all carburetor passages with an aerosol cleaner or compressed air.
Remove the adjusting screw (5), blow out its channel. Then screw it in until it stops and loosen, depending on the type of air filter, by 2 (foam, paper filters) - 2.5 turns (cyclone filters).
Assemble the carburetor.
The electrical system of gas generators is quite reliable. Most often, you can face two problems: lack of battery charging on generators with electric start or lack of voltage at the generator output .
The lack of battery charging is a consequence of the failure of the rectifier or low-voltage winding. It is easy to check this system with your own hands: connect a 12-volt light bulb in parallel with the low-voltage winding of the generator and start it. A lit light means that the generator itself is working properly, and it is necessary to replace the rectifier.
The absence of voltage at the generator output is most often the result of wear on the brushes. Remove them and assess the degree of wear, replace if necessary. If your generator is an inverter type, check if the voltage comes to the input of the converter by connecting a low-power 220 V lamp in parallel with it.

One of the routine maintenance provided by the instruction manual for gas generators is the control and adjustment, if necessary, of the valve mechanism clearances. An increase in clearances above the norm will lead to a decrease in engine power, an increase in noise during operation. The most dangerous is a decrease in the gap, since it is not audible during operation, but the pinched valves, especially the exhaust, begin to burn rapidly. As a result, the engine starts to work unstably and, when the plate is burned out, it stops starting.
Valve Adjustment Procedure pretty simple:
Remove all components that interfere with the removal of the engine valve cover.
Remove the spark plug.
Remove the valve cover.
Set the crankshaft to top dead center of the compression stroke by the mark on the flywheel (if any) or by controlling the movement of the piston through the spark plug hole. Do not confuse compression TDC (both valves are closed ) with TDC issue (the outlet valve closes, the inlet valve opens ).
Loosen the locknuts of the adjusting screws and, using a flat feeler inserted between the rocker arm and the end of the valve, set the clearances by turning the screw. Typically, a clearance of 0.2 mm is adopted for the outlet valve, and 0.15 for the inlet valve (check in the operating instructions).
Tighten the locknuts and turn the crankshaft twice to TDC. If everything is done correctly, at the next dead center both gaps will go away, after another turn they will take the set value. Increased gaps after the first revolution are a sign that they were adjusted at TDC of the exhaust stroke.
Assemble the generator.
Manual starter malfunctions - perhaps the most common mechanical problem ... Either the cable breaks, or the starter refuses to rewind it due to a broken return spring, or the ratchet does not turn the crankshaft.
Remove the starter by unscrewing the bolts around its casing. By unscrewing the screw (1), the ratchet can be removed. Check its cams (4) and return springs (5). Then carefully remove the pulley with the spring (7). Replace a broken cable or broken spring, whichever caused the repair.
When reassembling the starter, care must be taken to ensure that the spring remains in engagement with the shroud and pulley during installation. The cable must be fully wound around the pulley. With the ratchet in place, check the cable travel and how the starter returns to its original position.

Sometimes it happens that the generator needs to be started urgently, and the recoil starter failed at that very moment.There are several emergency start methods if necessary.
The methods listed below unsafe !
Remove the starter cover. A flywheel with a cooling impeller is located under it, which is pulled to the crankshaft by a nut. To make it spin, you can:
With a rope wrapped around the flywheel, use it in the same way as a recoil starter rope. Note that if it snags on the fan blades, the rope will turn into a whip whip when starting the motor, so be careful. Stand so that the rope cannot get caught in your hands or head.
Low-power engines can also be started manually: with the ignition off, turn the crankshaft several times, turning the pulley by hand in the desired direction. In this case, the gas valve must be open, and the shutter of the starting device must be closed. After that, turning on the ignition, bring the crankshaft to the compression TDC (you will feel an increase in the effort on the flywheel), and then turn the pulley with a sharp jerk so that the spark energy is enough to ignite the mixture.
A powerful cordless drill and an extension head from the tool kit are a good replacement for a quick electric starter. Clamp the extension in the chuck, put a head of a suitable size on it and unscrew the crankshaft by the flywheel nut. True, in this way it will be possible to start only a low-power generator - for a large-volume engine, the drill torque is not enough to turn it on the compression stroke.
A number of faults, alas, are quite difficult to fix with your own hands, without sufficient qualifications: for example, a faulty inverter converter or voltage regulator can only be repaired with a good understanding of the principle of operation and circuitry of such devices. Not every owner of a gas generator will take up the engine bulkhead, although this is not as difficult as it might seem.
In this case, it is worth contacting a specialized repair shop. You can find out the coordinates of workshops in your city on the Internet or in shops selling gasoline-powered tools.
In large cities like many workshops , here are just a small part of them:

In large cities like many workshops , here are just a small part of them:
Checking the gas generator for noise
If, when you turn on the gasoline generator, the muffler starts to shoot, another noise occurs and flashes are visible when you pop, then we will try to identify the possible causes of the gas generator malfunction:
First, the spark plug is out of order;
The second cause of the malfunction is incomplete combustion of gasoline in the cylinders;
Either not tightly closing the exhaust valve and letting it pass burning fuel into the muffler;
knocked down angle of ignition or opening of valves, this gives flashes.
Gasoline generator repair methods
Correct the ignition of the gas generator (replacement of the spark plug).
Clean or replace the air filter.
You can also check the tightness with which the valve is seated against the seat. In the simplest case, you need to unscrew the block head cover (when the outlet and inlet pipes are not screwed to it).
Check if the valve timing and ignition timing are set correctly. It can get lost from the working vibrations of the unit - the locking bolt that fixes the magneto is gradually unscrewed.
When the engine of the unit does not start immediately, you need to arrange a small technical inspection. Check the fuel level, gasoline generator oil, spark plugs and filter. It is unacceptable if the candles are dirty or cracked. Replace damaged ones, clean dirty ones with a wire brush. Remember that the generator must cool normally; if it overheats, the power section often fails.
If the voltage is completely absent, disassembly of the gas generator and its inspection is necessary. In this case, the problem may be caused by several points: lack of contact, faulty brushes, burnout of the PWM unit, capacitors, etc. When the motor speed is stable, but the voltage constantly jumps, then the excitation regulator is most likely damaged.
Before you change a burnt-out block, you will need to find the exact reason for its failure.
Do-it-yourself minor repairs of gas generators, most often, are needed in case of failure of candles, air filter, lack of fuel and oil. Without them, most models simply will not start, since the built-in protection is triggered. Constantly monitor the condition of the mesh at the fuel filter and the cleanliness of the air filter.
A missing ignition spark may also be the cause of the problem. To solve it, unscrew the candle with a special key, clean the carbon with an emery cloth and an iron brush, wipe it well with alcohol and dry it. Then check for spark and start the unit. Please note that carbon deposits are deposited if low-quality gasoline is used, as well as when the fuel does not completely burn out.
It may still be necessary to adjust the carburetor.Soot often occurs due to the fact that the generator is operating at an incomplete capacity. It is better to trust the specialists for big problems. If you do not have sufficient skills, it is better not to try to fix them. We carry out repairs of gas generators of any modifications.
There are two main types of generators: industrial and domestic. They have different power, dimensions, fuel consumption, and so on. The principle of operation is identical. The main differences are:
The household model does not have a large resource, therefore it is intended for short-term use only. Power does not exceed 2-3 kW. Produce a single-phase current of 220 V.
Industrial models are designed to run smoothly over a long period of time. The power can be incredibly high, depending on the system being served. Produce a three-phase current of 380 V.
When purchasing, the choice should be based on the conditions in which the equipment will be used. It is important to understand that a homemade gas generator is not as efficient as a manufacturer's model.
The main mechanism is a gasoline engine, the principles of a gas generator are based on it. Currently, two-stroke and four-stroke versions are used. The first type has a simple design, is lighter and cheaper, but at the same time has a minimum resource and is not intended for long-term use, although it is usually suitable for household purposes. But more often they choose four-stroke models, they fulfill their purpose in full.

The generator is the main working unit of the equipment that generates electric current. When the rotor moves, current is excited on the stationary stator, due to the alternating magnetic field. In fact, the presented aspects of physical strength and theory do not really matter. To eliminate the malfunction, it is enough to change some parts, since they cannot be repaired, but only replaced. A gas generator wiring diagram may be needed, where it will be possible to more thoroughly study the main aspects. There are differences in power:
Low-power power plants with indicators up to 2 kW. Used for short-term starting. Most often, they serve small refrigerators or to illuminate the area with several bulbs.
Medium type models with power up to 6.5 kW. The equipment is used to provide electricity to small houses, garages or shops. These are professional systems that run exclusively on gasoline engines.
Powerful electric generator up to 15 kW. Unique systems, where not only a gasoline engine, but also a diesel engine can be used, it all depends on the manufacturer. All models are only three-phase and are used to supply power to huge buildings, enterprises or industrial facilities.
Consumers have the opportunity to replace a generator or engine in any segment, but this should be done only after thinking over all further technical indicators in advance. That is, you can make one of two gas generators if some parts are damaged and unsuitable for further operation.

Gasoline engines are most often installed on generators, of course, there are models that run on diesel fuel, gas, but they are less popular. Various breakdowns occur during operation, and sometimes their elimination requires urgent intervention. Only in this way will it be possible to achieve the required indicator. Considering the main types of breakdowns and defects, it all comes down to the fact that they are always identical. The design of the motors is the same, and they differ only in technical characteristics, so it will be much easier to eliminate engine breakdowns than the generator. Major malfunctions:
The engine will not start. There is no fuel or spark on the spark plugs, the integrity of the crank mechanism is broken. There are defects or extraneous elements that prevent this.
Equipment operation is uneven and intermittent. The fuel has impurities, the spark plugs are malfunctioning.
Breakdowns associated with the crank mechanism. Most often this leads to the fact that there is a fuel supply, like a spark, but the engine does not start. There may be no compression due to wear on the rings.
Sometimes on Chinese models, pistons break off, as low-grade metal is used.
Poor quality oil can also clog the ducts, leading to overheating of the motor.
The clogging of the carburetor occurs due to low-quality fuel, the ingress of impurities or prolonged non-use of the equipment.
Technical issues are resolved only through specialized service stations. If there is a guarantee and service in the city, then the choice is completely obvious. In this situation, nothing can be disassembled, since specialists will refuse free repairs, due to a violation of the integrity of the structure. Therefore, you need to check the warranty period first.
The equipment has many different additional parts and mechanisms that fulfill their technical tasks. The installed inverter muffler is part of the soundproofing. When using a gas generator, a lot of noise is emitted, so it must be minimized. Developers are trying with all their might to create more advanced systems of these devices.
Regarding the presented aspect of the repair work, it is recommended to contact specialized service stations. You can buy a new generator for a gas generator and install it yourself, otherwise you cannot do without the help of specialists. The main types of breakdowns and methods of elimination:
The generator does not produce electricity or is intermittent. Violation of the integrity of the electrical circuit, the winding is damaged, the motor does not transmit torque.
A burning smell appeared. The generator has burned out, a short circuit has occurred.
For any type of violation, it is recommended to stop the engine immediately. Further, an external examination is carried out or a master is called. The second option will be more rational and efficient.
A starter is required to start the engine. Most often, manual is used, but more powerful models are equipped with electric starters similar to automobile ones. Repair and maintenance of these technical elements is carried out by complete replacement. The problem is that most of them are not repairable. Routine disassembly can lead to the fact that you simply cannot put everything back.
The main condition for carrying out repair work is to refer primarily to the technical manuals. This will allow you to deal with all breakdowns and other restrictions in advance. Your hand will be the ultimate guide for repair and maintenance. Electronic components are checked using specialized stands. That is, it is computer software that will allow you to identify all the flaws in the equipment at an early stage.
Regardless of the type or brand, all gasoline generators are serviced in the same way. For the convenience of consumers, special manuals and recommendations are attached to the equipment so as not to forget about the planned maintenance. You must always start with an external examination, so as not to miss damage to external parts. Of course, if you have a Chinese inverter generator, you may have problems finding components. The main types of work included in TO:
The inspection should consist of viewing all work items.
It is necessary to remove the air, fuel filter and replace it with a new one. The duration of the shift depends on the duration and frequency of use of the equipment.
It is recommended to replace belts, candles.
A standard stand-alone generator requires regular oil changes.
Based on the aspects presented, it will be possible to increase the service life of the equipment to the maximum.
You can replace a wheel with mobile equipment without any particular problems.
It is recommended to pay attention to the Fubag technique, this is a German brand that produces new generation electric generators. This option will be able to fully satisfy all the individual wishes of customers. The company produces various types of equipment models with different technical characteristics. That is why you can easily pick up everything you need without any restrictions.
Of course, in order to properly carry out maintenance and repairs, you need to know the device of the gas generator, then you can not only change the parts, but also put it back together. This is not so easy to do, since there are a large number of different nuances that are recommended to be studied at the preliminary stage.
Any equipment requires professional care. Therefore, it is recommended to adhere to the rules that the manufacturer provides to customers. These are very important aspects that will not only improve the start-up of equipment, but also increase the turnaround time. Key recommendations:
For long-term storage, it is imperative to drain all fuel from the tank. Gasoline oxidizes carburetor parts, which can clog the passages.
It is recommended to use polyethylene to cover the equipment during long-term storage, to protect it from corrosion and moisture ingress.
It is best to carry out maintenance before storage.
In no case should the generator be left disassembled for a long time, as foreign elements can get inside.
Store in a cool, dry place.
Do not start up equipment in extreme frost if it is not designed for use in such conditions.
Thus, you can protect not only your money, but also your equipment. Currently, manufacturing companies provide customers with special technical instructions that go into all the details in detail.
