Good Fortune!

Wild guess --- is petcock allowing fuel to drain toward carb vacuum nipple through the vacuum tube from carb to petcock (perhaps due to petcock diaphragm damage)?

Good Fortune!

ok so my dumb self... i pulled the carbs off put on a bench and connected fuel line and it was leaking out were the line went into the carb..tighted up the line seemed to have stopped...will let it sit for a few days then recheck thats when it leaks after it sit's for a week or so...keep u posted

There's a carb fuel intake tee fitting between the middle two carbs.

Maybe all the fuel leakage was from just a loose fuel line where it attaches to the tee.

With the "correct" size fuel hose i.d., it's often unnecessary to use any type of clamp when attaching the fuel hose to whatever fitting.

I use the best non-kinking type fuel hose available, with smooth curves, usually without any clamps, and suffer no leakage whatever.

If leakage persists after tightening the attachment of fuel line to the tee, would then suspect damaged or deteriorated o-rings on the tee where the tee fits into the carbs.

Good Fortune!
