yea gettin a HMF slip on sport seriouse, now on Dynojet jetting what do i put in a 155 main? and like a 42 pilot? now correct me if im rong does the pilot regulate flow of fuel when the engin idles and just startes up like will it help it on a cold start? mines a S.O.B to keep running when its cold out and when its just on a plain cold start in summer,

Yeah thats correct. I am running a 155 main Dynojet and a 40 pilot and I live in Michigan. When its cold, I just pump the throttle a couple times and it starts right up.
