Re: what did you do to your motorized bicycle today?
Cruise, electricity travels at 186,282.397 miles per second. Changing the gap on the spark plug a few thousands of a inch will not affect the timing.
Perhaps you were thinking of changing the gap on the points of a traditional points/breaker style ignition? Changing the gap on that will definitely affect the ignition timing.
