Just got a 78 spitfire 340 and im having some running issues. Biggest issue is I have no clue what was done before me.
Stator was out but I reassembled it and it fires up and idles pretty decently. Give it throttle and it just bogs down. I can hold it there and it wont rev up at all. Spits gas out intake. Compression is about 90-92psi per cylinder. I see it has what im assuming is not the original carb. Mikuni 38mm (measuring intake side). Tried a second CDI that came with it and same issue. left cylinder doesnt fire as much as right but sometimes it does even out. I am wondering if the carb is to big and flooding it out. Choke makes zero difference but I did loosen the adjustment so it seems to be fully closed as I was suspecting it was partially open.
Any ideas? Ill see if an old 340 I have in back of shop butterfly carb will change anything if it fits.

Re: 78 spitifre 340 running issues
got it figured. The timing marks on the stator are way our. Must have a different backing plate on stator. have it cranked all the way to left and it fired and reved up...i guess its a lesson to check simple things first. didnt think stator timing would affect it so much.
