I have a question about a FA50 I bought last summer and did some work on to try to get running again but still seems sluggish.
Below is a list of what I have done to the FA50.
Cylinder bored and honed
New oversized piston
new spark plug
good tire pressure
however my compression runs around 75 which seems a little low to me? (am i wrong?)
I weigh 135lbs
the thing only tops out at 18 mph and its to the point where I don't know what else I can do to it. Could the timing be off for my ports? If so how would I adjust this? I am open for any suggestions.
