i just totally rebuilt my motor , 50 over , weiscos , v force , fmfs , k+n no lid, +4 timing, slight porting , stock carbs with vitos jet kit ,300 main, needle middle clip,air screws 1 1/2 out.
took it out , ran good for a little while 30 min. then would bog and stall , then would start up and run good ,and then after a little while happen again , thinking maybe its jetting , the vitos needles are longer i think , are these jet kits any good ?
does this jetting sound close , i live in new york (sea level)
if it was jetting wouldnt it run crappy all the time ?
jet kit says for pipes , k+n no lid
came with 300 and 290 mains , maybe better with 290 , what do you think?
