Fuel issues again...help

[jphillips]

Guys ran the snot out of my SECA all weekend. Let it set and the same hemmorage. Took the vaccum line off number one to the petcock and there was a slow drip. On a hunch, pulled all plugs, pulled the wires back, put it in second and slowly turned the engine over. Sure enough it threw a full cylinder of gas out like spit. It only came out of cylinder two?
Is that put in a new petcock? Or a float issue on number two cylinder? Do you have to cut off the petcock after each ride? Never had to on all of my other bikes?
One other thing, one time it would not rev at all when it started, I had to use the choke to gun it and then when it got hot the throttle worked? Is this related, my guess is it was super flooded?
Remember the bike was trashed and you would not believe all of the goop I cleaned out of the carbs.
Not gonna give up!
