Default Re: New engine worries ( 1st build)

The dealer may have had issues telling me what might really help but they ended up sponsering me later on once I started winning races (loved the free parts and stuff!) I honestly don't think I ever found the real problem just worked around it, I eneded up re-jetting the carb for a leaner mix, running a super hot plug and leaning the fuel mix out to 50:1 and it didn't foul as often so I could make it through an entire race but I was still changing the plug inbetween races bc if it didn't foul the first race it would on the second, there were days where I would have to let it warm up with one plug and then wait for it to foul bc it always would once warmed up and I would change plugs even before the race!
