Ignition Timing Adjustment - RCGF 26ccBM Operator's Manual

Ignition Timing Adjustment

The ignition timing is preset on the RCGF26cc at 28-30° before Top Dead Center (TDC).
The ignition timing can be advanced or retarded by loosening the ignition sensor Phillips
head screws and sliding the sensor to the full extent clockwise (32° advancing the
ignition) or counter clockwise (26° retarding the ignition). Be sure to retighten the Phillips
head screws after adjusting the ignition timing. It is best to attach the sensor with the
screws centered in the slot as a starting point.
Advancing the timing causes combustion to occur earlier resulting in
higher performance of the engine. However, advancing the timing also
causes higher engine temperatures and can cause premature wear of
internal engine components.
