First I'd look at the vacuum line running off the petcock to make sure it doesn't have any cracks. That could starve you for fuel at WOT.
Second, I'd look inside the tank and see if you have any tank liner that's flaked off. It could be blocking the screen of the petcock.
If you remove the petcock I would advise having a diaphragm and screen kit on hand. Once one of the old vacuum petcocks it disturbed they leak a lot of the time.

Yep I agree. The rubber diaphragm in the pet **** could have crack in it as well.

I have a gravity pingel pet **** no vacum line.
And i will check the liner and float bowls next. I feel it might be a manifold leak. I lost a beeather bolt that holds my valoscity stack and the other one backed off. Maybe the carb rattled to much once loose and tore the gaskets.
