Sometimes carburetors have two adjusting screws, which are made to simplify configuration. The exact data on the carburetor setting must be extracted from the operating manual, but it is better to entrust this operation to specialists, since this is a very difficult and responsible job.

Problems in the ignition system of a chainsaw can be judged by the following signs:

• The engine will not start;
• The engine starts, but rushes almost immediately;
• The engine is unstable;
• Don’t develop full power or stall.

You should start the ignition system test by checking the spark plug. The plug must be clean, free of carbon deposits and not filled with fuel mixture. The gap between the electrodes should be 0.5-0.65 mm. The carbon from the candle can be cleaned with a sharp awl, the electrodes should be cleaned with fine sandpaper.

Starting problems can also occur due to damage to the spark plug seal plug or wear. Then we test the spark for a spark. To do this, connect a high-voltage wire and, holding a candle with pliers with insulated handles, apply it with a thread to the cylinder. By pulling on the starter cord, we check for a spark. If there is no spark, then the spark plug must be replaced. If there is no spark and new spark, then the problem should be looked for in the high-voltage wire.

How to replace the starter cord of the Stihl 180 chainsaw. Stihl 180 ignition adjustment

On Stihl MS 180 chainsaws, an electronic ignition system is installed, the adjustment of which is reduced to setting the gap between the flywheel and the ignition coil of the Stihl 180 saw. To adjust, remove the starter, loosen the two screws securing the ignition coil and install a strip cut from a plastic bottle between the flywheel and the coil contacts tighten the fastening screws.

To check the clearance, it is necessary to turn the flywheel and check whether the coil contacts touch it.

The device and principle of operation of the chainsaw starter

All types of chainsaws, both Chinese and European, are equipped with starters of an identical design and principle of operation. The universal design of starters allows these devices to be used both on branded chainsaws and on semi-official tools supplied from the Middle Kingdom. It is important to note only that domestically produced instruments have some distinctive features.

The chainsaw starter is a simple mechanism consisting of:

• Drum.
• Rope.
• Handle connecting with a cable.
• Spring return frame.

The principle of operation of such a device is also quite simple. When pulling the handle, which is connected by a cable to the drum of the ratchet mechanism, it moves. The drum, when moving, engages with the splines of another drum, which is located on the shaft. Thus, the saw crankshaft is manually moved, which makes several revolutions. As soon as the handle returns to its original position, aided by the return spring, the spline connection is lost, causing the shaft to stop. With each movement of the crankshaft in the cylinder, the amount of the fuel-air mixture increases, which ultimately contributes to its ignition.

The more power the tool has, the more jerks the starter has to make to start the engine. The return spring is responsible for accelerating the return of the drum to its original position, the manufacture of which is carried out using steel with a high degree of elasticity.

Over time, with constant use of the tool, there are problems with starting the engine, or rather, with the functioning of the starter. If such problems arise, the starter can always be repaired. If the principle and device of the starter is known, then it will not be difficult to repair it with your own hands.

Replacement of oil seals

How to repair a Stihl 180 chainsaw if oil seals need to be replaced? It is necessary to disassemble the engine, for which you first need to remove it from the chainsaw.

After the engine is removed, the 4 screws securing the engine tray are unscrewed, after which it is removed. Thus, removing the pallet, we gain access to the oil seals and bearings of the crankshaft.

An important point when replacing oil seals is to reinstall and seal the pallet.

To carry out it efficiently, it is necessary to clean and degrease the pallet and the place of its installation on the saw cylinder, and then coat with sealant and install the pallet by tightening it crosswise to the required force.

At the time of installing the pallet, it is important not to confuse the location and install in such a way that the casting to hold the oil pump housing is located in the opposite direction from the flywheel, otherwise it will be impossible to put the engine back into the saw body.

Assembling the chainsaw after repair is carried out in the reverse order.

Doesn’t develop momentum

If the saw does not maintain idle speed, then the following may have happened:

• Clogged filter;
• Violation of the ignition system;
• The carburetor has deteriorated;
• Motor parts are deformed.

For self-repair, you need to follow these steps:

• Flush or replace the fuel hose.
• Clean filter.
• Check the quality of gasoline and oil.
• Check the operation of the carburetor and spark plugs.

When the Stihl chainsaws are repaired, they will work correctly.

If the saw is not gaining momentum, then this could lead to:

• Defective engine;
• Cylinder wear;
• Failure of piston rings;
• Broken spark plug;
• Coil malfunction;
