I have a 82' Yamaha with two carbs, replaced the seals, etc, even the drain plugs/o-rings and I go to fire the bike up and gas leaks through the bottom bowls and the drain plugs still. I was wondering if the Petcock could be allowing too much gas through or what other things could be causing this? Any help would be awesome.

Thanks.

This would be better in the trouble shooting section.

I don't think the problem is your petcock if your losing gas out your drain plugs. Try an automotive (gas resistant) o-ring on the drain bolt and see if that helps.
