C.
Spark Plug
a. Remove the spark plug and inspect it each time you change the oil. (Use
a spark plug wrench) The electrodes should be kept clean and free of
carbon. The presence of carbon or excess oil will greatly reduce proper
engine performance. If possible, check the spark plug gap (area between
electrodes) using a wire feeler gauge. This specification is 0.025"~0.030".
b. Before installing spark plug coat threads lightly with graphite grease if
possible, to ensure easy removal next time the spark plug needs inspection.
c. It is advisable to replace the spark plug at least once a year to insure easy
starting and good engine performance.
D.
Carburetor Adjustment
Never make unnecessary adjustments. The factory recommended settings are correct for most applications. It's not
necessary to disassemble the screw unless the carburetor needs to be replaced. Prepare a 50r/w tachometer
before adjustment.
