Stihl MS 390 Problems and Solutions

some common problems with the Stihl MS 390 chainsaw and their solutions:

Clogged carburetor: This is a common problem with chainsaws, and it can be caused by a number of things, such as old or stale fuel, dirt, or water. To clean the carburetor, you will need to remove it from the chainsaw and disassemble it. Once it is disassembled, you can clean the jets and passages with a carburetor cleaner. Be sure to follow the instructions on the cleaner carefully.
Bad spark plug: A bad spark plug can also prevent a chainsaw from starting. To check the spark plug, remove it from the chainsaw and inspect it for damage. If the electrodes are fouled or the porcelain is cracked, the spark plug will need to be replaced.
Low compression: Low compression can also prevent a chainsaw from starting. To check the compression, you will need a compression gauge. Attach the gauge to the spark plug hole and crank the engine. The compression reading should be at least 100 psi. If the compression is low, you will need to rebuild the engine.
Fuel system problems: The fuel system can also cause problems with a chainsaw. If the fuel lines are clogged or the fuel filter is dirty, the chainsaw will not start. To check the fuel system, you will need to remove the fuel tank and inspect the lines and filter. If they are clogged or dirty, they will need to be cleaned or replaced.
Ignition problems: The ignition system can also cause problems with a chainsaw. If the ignition coil or spark plug wires are damaged, the chainsaw will not start. To check the ignition system, you will need to use a multimeter to test the coil and wires. If they are damaged, they will need to be replaced.

Here are the steps on how to fix a clogged carburetor on a Stihl MS 390 chainsaw:

Disconnect the spark plug wire from the spark plug.
Remove the air filter cover.
Locate the carburetor and remove the air filter.
Loosen the screws that hold the carburetor in place and remove it from the chainsaw.
Disconnect the fuel line from the carburetor.
Remove the bowl from the carburetor.
Clean the jets and passages in the carburetor with a carburetor cleaner.
Reassemble the carburetor and install it on the chainsaw.
Connect the fuel line and air filter.
Reconnect the spark plug wire.
Try starting the chainsaw.

If you have followed these steps and the chainsaw still does not start, you may need to take it to a qualified technician for further diagnosis and repair.
