98 Sprint Exec won't run

[Archi]

I let the Exec sit for a week without starting or driving it, and now it won't keep running and fuel pours out of the petcock. Wazzup with that!?!?

Perhaps the petCock has failed, or a hose attached to it! - With the tank off, fashion from a plastic milk jug, some JB weld and some tubing a fuel tank/supply - you will have to block the vacuum tube that attaches to the old petcock with something temporary, a pencil or the such like - and see if she'll run. If she does replace the petcock - Pingle does one but you will gain a hole in your body work and will have to make that vacuum hose shorter and block it up more permanently but the problem will go away for good! :razz:

Welcome to the "Mikuni's revenge" club. My petcock went south as well. I bought a new one from the factory and it has been fine since. I understand there is a rebuild kit available. My replacement cost $90 I think.

Thanks for the input, guys. I found the problem. The vacuum hose from #3 carb to the petcock had a tear in it right where it bends 90 degrees to the petcock nipple. I cut the bad part off, slipped it back on, and we're back in business!
