Carburetor Adjustment
Never make unnecessary adjustments. The manufacturer 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 the adjustment.
a. Warm up the engine for about 5~10 minutes;
b. Tighten the airscrew gently and back out 2-3/8 turns
anticlockwise;
c. Connect the tachometer, and adjust the throttle to limit
the idle speed (the standard value is 1500±100 RPM);
d. Slowly turn the airscrew anticlockwise; observe the
RPM of the engine, and stop the adjusting as the RPM
reaches the top speed;
e. Adjust the screw, and adjust the idle speed to an ideal
value;
f. Repeat the steps d and e until the rotate speed of the
engine becomes stable.
