thx for the replies
Its a pull start motor, I have no starter box yet, so when the one way gets oiled up, well, you know the story..(its a pain) :P I do have a tendency to leave the glow stick on the plug while im pulling to try dry, or start. this can be from 10secs to a minute long.
Is that too long ? :/
The plug is clean and oily on removal. Is this a sign of too rich a setting ?? (but see below :/)
Im using 15% nitro, synthetic based.
The motor is, too what I consider, fairly well tuned, i have a home made idle screw in it, but works as factory.
It doesnt bog on full throtle from standing starts, wheel spins fine :P. It accelerates fine to top speed, and holds it fine, with smoke coming from the exauhst as normal.
I havent a temp gun/probe but a basic spit test leads it to be fine in my opinion.
Just at a loss still.. Any suggestions on plugs ? Higher/lower nitro maybe ? problems internally ?
