As it has been said before...diagnosing over the internet can be difficult but I'll do what I can to help.
The orig. plugs were fouled, so they were replaced before the salvage carbs were put on & btw the 2x we had the orig set on b4 the damage was done to 'em. The only reason for the 2nd set of carbs is 'cuz my friend bent one of the butterfly valves or I'd still be using the originals. When my friend's cowkr started wrenching on it, he thought maybe the rings had seized, so he took out the plugs & poured Marvel's Mystery oil in the openings to free 'em up. It sat for it to work its way thru, then the bike either peed, puked or smoked (exhaust) it out, lol. It would turn over after a cpl times trying & run for a long time, 20ish minutes, give or take, be completely warmed up... sometimes one of 'em would adjust the choke & it'd start to idle down to pt of wanting to stop & when it did shut off, it wouldn't turn bk over.
The last time the wrencher noticed the tank was rusted completely on the inside. Took it off. I took it home, after we'd drained it of all the gas possible, hosed it out, threw in 2 one-ft lengths of galv chain & shook it, drained it, filled it up, shook & drained again repeatedly. Took the petcock off prior & cleaned it up too being careful abt the diaphragm. I worked on the tank the 2nd day for 6 hours straight & 4 hrs the 3rd day before I used the last bottle of alcohol to evap. as much of the water as poss. Chains were out & I left it open, but covered all openings w/ breathable fabric to keep out any guests while it dried. We've now put on an in-line fuel filter. Still using aux tank till we fig out what's wrong.
This last time it ran for the same amt of time approx. & the wrencher was adj the sync on the carbs & my bud was messing w/ the choke too when it shut off & wouldn't start bk up. From what I know the sync is to be at 2 & he had it at 1 7/8. That's all I can think of right now, but if I remember any more tidbits I'll post an update.
Thanks for giving it a shot
