1.How long has the chainsaw been used?
This is very important. If you just used it, it may be an incorrect startup flooded the engine.
Strictly speaking a flooded engine is not a fault. This situation is quite common. Remove the spark plug, gently press the spark plug port with your thumb, pull the start handle a few times to drain the excess fuel in the cylinder, dry the spark plug and install it back, and then restart the chain saw to solve it.
2. Is the fuel mixture correct?
This is also very important. The chain saw works normally in the morning and cannot be started at noon. We need to remove the muffle first to check whether the piston is scratched. If it is cylinder scuffing, the cylinder body needs to be replaced and professional maintenance is required.
Finally, I will give you a way to maintain the machine. If you do not use the machine for a long time, you have to pour out the oil in the fuel tank. Start the machine to burn out the oil in the carburetor and cylinder, so as not to block the carburetorwith residual oil. Clean the air filter more often, and use better lubricating oil.
