Warm Tips: 1. If the engine is failure to start normally under the normal ignition and cylinder compression, it is likely that the carburetor needle will need to be adjusted. 2. After tightening the main oil needle on the carburetor, loosen 1/4 turn and start the flywheel to make the mixture ratio of gasoline and air reach the normal working mixture ratio after several times. 3. Turn off the power switch when the machine stops.
