    Just a note: Vince gave me some good advice that helped me with jetting. "Keep a log of all the changes you make"

    It rolled under power last night after some confusion. It ran for about a minute, then I flipped the choke closed and it quickly died, and I didn't get it started again (got tired of bump starting due to broken kick start lever). I am assuming I am grossly rich, since I have a 310 main jet in, and my research says that people are running a 280 with a similar setup. I have a 145 PSI compression.

    What spark plug should I be running... the long one or the short one...(version of whatever the hell I am running stock and DR)

    shorty I think. 145 compression is good. def try a leaner jet. is your idle jet right?
