Question: I use a Stihl MS 361 chainsaw. Tell me, are 3/8 (1.6) ring sprockets suitable for 3/8 (1.3) chains? Will the low profile chain dangle from the big sprocket?
Answer: For a crown, or in other words, a ring sprocket, in interaction with a chain, the main parameter is a step, and the thickness of the driving link can be any from 1.1 mm to 1.6 mm. The main thing is that there is the same pitch of the chain and the leading sprocket.
If you paid attention, the crown itself has some freedom of movement along the axis of rotation. This is done to make the chain run smoother, reducing vibration caused by the moving chain.
If the chain shanks could still “dangle” from one side wall of the sprocket to another, naturally in the presence of normal chain tension, then this would be a blessing on the contrary, the sprocket resource would increase, because its teeth would wear out evenly over its entire surface.
Usually it is quite the opposite, the chain shanks choose one place on the teeth and during the operation of the chainsaw they begin to slowly “cut” this place, in especially advanced cases or in the presence of a low-quality asterisk, sawing the asterisk in two halves.
Question: how is it better to start-warm up the Stihl 361 chainsaw in the cold?
Answer: 1. I usually put the lever in the down position and pull until the first flash.
2. I put the lever in the middle position (half gas), looking for some.
3. As soon as the engine starts at half-throttle (the chain rotates), I hold it for about 5 seconds and only after that I do the rebase. When I do heat re-gasification immediately after starting.

Question: Chainsaw Calm MC 361, the carburetor does not obey the adjustment. What is the reason?
Answer: There may be several reasons. Air leaks are possible.
Question: Do I need to use an 8-tooth motor sprocket for ripping with a 361 Gauge Saw with Timmerjig?
Answer: Not necessary, but it is better to install an 8 tooth sprocket. The saw chain must be changed! The saw tooth of the chain must be sharpened at an angle of 10 degrees!
There is no spark on the chainsaw calm 361, how to check if the ignition is working, how should the gap between the flywheel and the coil be hit?
Visual inspection: 1) The wires visually look nominal (without melting, etc.); 2) The flywheel is not “blue”, the gap is 0.2 mm .; 3) It is better to put a new candle. If there is still no spark, then we can say with 90% certainty that the problem is with the ignition module.
Question: Please tell me what the symbol “N” stands for on the box of the STIHL 361 chainsaw, although the saw itself does not have this symbol?
Answer: The letter “N” on the box of the Stihl MS 361 chainsaw means that the chainsaw is assembled with a cylinder gasket 1 mm thick, especially for Russia, anticipating the poor quality of gasoline in our country. For models sold in Europe, use a 0.5 mm spacer.
When working with the saw it was calm 361, it abruptly began to gain high revs, did not react to the trigger. I drowned it out, now do not start.
There is a spark, after pulling the starter 20-30 times the candle is dry. I cleaned the carburetor, flushed it out, but the fuel does not come in (full tank of gasoline).
I disconnected the hose from the carburetor, gasoline does not go - I also cleaned the breather in the tank from it. The filter on the intake is clean - the result is zero. I filled it in a little - it started up with a half turn and stalled, we have no service. How to fix?
according to the symptoms, somewhere there is an air leak, I can only say that the malfunction is quite serious and it will not be possible to fix it myself. Do not torment the saw, it is better to unscrew the muffler and see in what condition the piston is, if it is smooth, then everything is fine, if the longitudinal stripes are bad.
Question: The clutch slips in the Stihl MS 361 chainsaw due to oil and dirt. How do I remove the clutch myself to clean the entire basket?
Answer: Pull off the lock washer with a screwdriver, remove the sprocket, now to twist the clutch you need to lock the piston, for this we remove the back cover, the top cover, unscrew the candle, insert the stopper into the plug hole, twist the clutch until rotation stops and unscrew the clutch (the clutch on the left thread).
Question: There is a problem with the Stihl MS 361 chainsaw. Maybe someone has come across a problem and will help you with advice.
The bottom line: the saw starts up perfectly while it is cold, rattles smoothly, but after several cuts, when it seems to warm up, idle starts to float, and as a result, after 10 seconds the saw stalls at idle.
If you turn on the gas, you can cut further, as before, there seems to be no loss of power, but without re-gas at idle it stalls again.
I removed the lid and checked the air filter, it was clogged with dust, but in my opinion it was not critical, it let the air through, and eventually replaced it with a new one.
The situation has not changed. He took off the candle, the candle was black, dry, rubbed it, checked the spark, everything seemed to be normal. In the operation of the chainsaw, nothing has changed again, it stalls at idle as before.
Replaced the candle with a new one, the result is the same. He began to sin on fuel, made a new mixture on new gasoline, the result is the same. Starts up like new, but no way with idle speed. Gasoline 92, oil calm HP.
The oil was bought from a dealer, the packaging is original. He seemed to not allow overheating, he worked for 15-20 minutes, he felt sorry for the saw, he fired half a barrel at a time, or even less. I sharpened the chain once a day, or even more often. In general, what do you recommend?
Answer: To begin with, turn the Calm 361 chainsaw carburetor adjustment screw half a turn to the right clockwise. But, most likely, nothing else is needed.
If it turns out that the chain is moving at idle, then you can gradually turn in the opposite direction. Ideally, there should be a steady operation and a fixed chain.
However, for a specific instance of a saw, it is quite possible that at the lowest possible idle speed, at which the engine is still running stably, the chain will at times “twitch” on the tire.
If this happens with your saw, you do not need to be afraid, but you also don’t need to forget about this feature.
Question: With prolonged hard work, the internal element of the muffler frays its body and broken pieces can get into the cylinder.
This happens apparently due to overheating. Is there anything you can do about it? I try to tighten the muffler when loosening the studs.
Answer: They have such a problem - with mufflers. I've experimented, on several saws (of those that periodically get to MOT) I did not put a gasket under the muffler. And it seemed that the mufflers did not fall apart much longer.

With all the variety of modern building materials, wood remains very relevant. Therefore, lumberjacks, workers of landscaping services, summer residents are interested in tools for woodworking, including chainsaws.
The Stihl chainsaw is easy to operate, inexpensive in price, reliable, has a long service life.
Different people prefer different brands. Someone is interested in the Partner chainsaw, someone is interested in the Shtil brand device, someone else is interested in something else.But they all break down from time to time, and their breakdowns are both similar and different. Next, consider the repair of the Stihl chainsaw with your own hands.
This brand is well known both among professionals and among individuals involved in arranging their own living space. The great popularity of the Stihl chainsaw determines the frequent practical use of this tool and makes us look for ways to effectively deal with its typical breakdowns.
The design of the Stihl chainsaw.
Before you start disassembling a faulty mechanism, you should prepare the appropriate tools. Since a chainsaw is a technically relatively simple device, this list is small and includes:
Screwdriver Set;
spanners;
set of socket wrenches;
igloo.
In order to carry out a full-fledged high-quality restoration of the working condition of the Stihl chainsaw with your own hands, it is necessary to accurately establish the causes of the breakdown. Since the specified chainsaw refers to mechanisms driven by an internal combustion engine, the main malfunctions are associated with this unit.
The most common in the operation of the Stihl chainsaw are the following malfunctions:
lack of engine start;
unstable operation of the internal combustion engine immediately after starting, as a result of which, after a short time of operation, the power unit shuts down spontaneously;
the running engine does not reach full power;
oil leaks.
Stihl chainsaw carburetor device
One of the frequent breakdowns of the saw device is also an open circuit in the working chain. But it does not apply to problems that arise during the operation of the motor system. Usually, repairing a broken chain boils down to replacing it with a new one.
The search for the malfunction that led to the failure of the chainsaw is carried out in the following order. First of all, the level of gasoline in the tank is checked. If everything is in order with the level, you should proceed to inspect the starting device. If the trigger does not show any signs of breakage, you must pay attention to the spark plug.
If, as a result of a thorough inspection and checking the correctness of the gap, it is found that the spark plug is in good working order, then the carburetor may be the cause of the malfunctions that force the chainsaw to be repaired. This often happens due to the fact that this device is corny clogged.
However, if the old plug is replaced with a new one, the carburetor is completely cleaned, and the chainsaw still does not start up or, once it is working, it stalls quickly, then a faulty cylinder-piston group (CPG) may be to blame for everything. In order to qualitatively check the entire group, you will have to spend some time, almost completely disassembling the specified system. In this case, the technical condition of the cylinder, piston and piston rings is checked.
And now we will consider each malfunction in a little more detail.
As mentioned earlier, the examination of a faulty sawing tool must begin with establishing the presence of gasoline in the fuel tank, as well as with determining the technical condition of the breather.
Repair of the Stihl chainsaw in case of a malfunction of the fuel supply system.
When checking the fuel level, it is imperative to open the gas tank cap. This must be done even if the owner of the tool has confidence that there is gas in the tank.
Often the saw cannot start due to the lack of fuel in the combustion chamber. The reason for this is most often the usual clogging of the breather - a special bypass valve, which serves to equalize the pressure in the tank with a gradual consumption of gasoline. In this case, the repair of the chainsaw comes down to careful cleaning of the breather with an ordinary sewing needle.
The cause of failure of the entire tool may be an inoperative trigger or problems in the ignition system. If it turns out that the starting device is operating normally, then you need to make sure that the spark plug is in good working order.In order to do this, the candle is turned out of the socket and carefully examined, paying attention to the presence of foreign plaque on its electrodes.
Chainsaw starter device.
It is worth noting that the presence of traces of a certain property in the place of spark formation speaks very eloquently about the sources of the "disease" of the entire launching system. Such a source, in particular, can be a carburetor. So, the complete absence of any signs of fuel on the plug (its complete dryness), most likely, indicates that the fuel does not pass into the combustion chamber due to the complete clogging of the carburetor.
If the gasoline is fixed on the chainsaw candle, and the cutting device itself does not work normally, then this indicates an excess of the air-fuel mixture. The reason for this condition, perhaps, is a malfunction in the carburetor adjustments, clogging of its nozzles, as well as improper start of the mechanism. In the case of a characteristic soot fixation on the candle, one can speak with sufficient confidence about the malfunctioning of the carburetor or about the use of low quality gasoline.
With all the above signs reflected on the spark plug, it is necessary to remove the carburetor and check its technical condition. If a blockage is found, the carburetor should be thoroughly cleaned, then the device should be adjusted according to the technological requirements and the gasoline used in the tank should be replaced. At the same time, you must always remember that the carburetor is a rather complex assembly, consisting of many small components, parts and channels. Therefore, its repairs must be carried out with extreme care and accuracy.
In addition to restoring the carburetor, it is necessary to check the performance of the spark plug itself at the stand and, if necessary, set the correct gap in it. If you do not like the candle and its work at all, it is recommended to replace it with a new candle.
Sometimes the engine of the tool does not start or works with obvious interruptions and without reaching the rated and maximum power due to a malfunction of the cylinder-piston group. In this case, do-it-yourself chainsaw repairs are performed in this sequence.
4 bolts are loosened on the cylinder head, after which the cylinder is removed from the block. The piston is carefully checked for chips, scratches, scoring. Their presence is unacceptable and entails replacement of the piston. At the same time, there should not be the slightest mechanical damage on the cylinder itself. It can either be repaired by bore a mirror to fit the piston oversize, or replaced with a new one assembled with a piston.
