he didnt claim the wouldnt work for his engine, just the slides and needles the come with them dont work very well. claims the pj are easy to adjust, but getting it to idle is harder. i guess only time will tell.
i dont know the whole story of you two but i do remember you tried 2 different needles. i dont know but some guys are trying 6 pair, maybe thats what it will take, shit if i know.
all i know is there are several guys on here with his engine and they run well. so you get all them to chime in with what elevation and what needles, jets that worked we will get it figured out
