350 screamer Posted February 13, 2012 Author Report Share Posted February 13, 2012 (edited) carb slides the correct sides? how about doing a leak down and compression test? its at 150 psi both sides im at 500-637 above sea level, with 4mm stroke and 5mm long rode, with reed spacers after the reeds to push back the carbs. the timeing is advanced +4. the pipes im running are FMF fattys and silencers. the cylinders are bored 20 thousands over.

guns4children Posted February 13, 2012 Report Share Posted February 13, 2012 spacer plate = no good Quote Link to comment Share on other sites More sharing options...
350 screamer Posted February 14, 2012 Author Report Share Posted February 14, 2012 spacer plate = no good Im puttin the 200 mains back in to see if she runns. maybe it needs to be smaller then a 280. Or since it runs better and actually fires in mid to high range rpms my pilot can go one size bigger? Quote Link to comment Share on other sites More sharing options...
