BenBB Posted November 12, 2003 Report Share Posted November 12, 2003 Who did the porting? I'd see if they have any jetting recommendations and octane requirements first. If not, I'd start with 350 mains, 30 pilots, airscrews 1.5 turns out, and needles one clip position leaner than stock (2nd notch from the blunt end). Should be a safe starting point and SHOULD be on the rich side (again, depends on the porting)...assuming normal 60-80 degrees F temps and 32:1 premix ratio. I would run a minimum of 50/50 race & pump gas to be 100% safe, race gas if you can afford it (or 21cc domes if you want to run pump gas safely). Good luck.
