Finally got the gas tank back in and fired my 59 2.5 ton up but it is not running right and in a way I havnt seen. I just rebuilt the carb, but for a while it would not idle without the choke pulled way out. I adjusted the point gap and it got better but not always fixed. The biggest confusion is that when i try to rev it, it sputters and sometimes dies but if i give it a half throttle for a second, it will stop firing, then rev up pretty high and stay there. Throttle isnt sticking open. Some of it seems like a vaccume leak but there are not many lines and when I actually disconnect one it runs worse. It also backfires out the carb and exhaust depending on choke/throttle. Not sure if any of it could be the governor? The only other vaccume option I can see is the brakes which also lost all their fluid with no visible leaks.

Thanks for the help
