AZZKIKER is an unknown quantity at this point
The petcock is vaccum operated by the engine and no gas should be coming out of it if the engine is not running. You are probably missing a gasket somewhere if gas is leakin out. Go to www.ronayers.com and check out the microfiche for the fuel tank and see if you are missing a parts somewhere. Good luck.

Vacuum operated petcock has a flexible plastic/rubber membrane in it. If it is damaged - petcock will leak, as petcock will not close when engine off. Small hole in petcock meant for draining out petrol that got "through" membrane. If it is leaking from there - you need new membrane. Those ususally available from Honda or aftermarket.
If it leaks from under petcock mount - that's different then, it means that ring seal under petcock flange needs replacement...

This may help:

There are 5 hoses that attach to your tank: 3 to the petcock and two overflow lines.

Petcock has the two main fuel lines and a small vacuum line. The other small hole at the bottom of the petcock, (I know what you are talking about) is not used.

I think Bluesman is referring to part #38, the rubber washer. Make sure that is in there, and that all your fuel lines are pushed in as far as they can go (there are little arrows printed on the petcock spigots.
