The reasons why the chain saw can not be started are:
1. The wrong operation method caused the chain saw to flood the cylinder. Strictly speaking, it is not a fault, and there are many such things;
2. Whether the fuel ratio is correct;
3. The spark plug may not have electricity;
4. Is there any scratch on the piston.
Check the oil circuit and circuit to see whether the oil filter is blocked, whether the carburetor is pumping normally, and whether the spark plug is energized. Remove the top of the spark plug, place it on the metal, and pull the machine to see if the spark plug is energized. Remove the air filter and check whether it is clean. Remove the carburetor, drop some oil into the cylinder, and run the machine several times.
If not, you must clean the carburetor or replace it, and check the cylinder block at the end. If you do not use the machine for a long time in the future, you must drain the oil from the tank. Run the machine and burn off the oil in the carburetor and cylinder. If the remaining oil blocks the carburetor, usually clean the filter more and use the lubricating oil well. In addition, oil seal damage, magnetic flywheel and crankshaft, crankcase and balancer are uncommon cases. When the above problems are not the cause, they can be considered.
