Check thast ptcock..it failed once so dont be so sure its good by any means. here is what I do to see if it leaks.
Get two soda bottles and two long length of hose. Put a line from the vacuum off the petcock to one bottle and a line from the fuel nipple to the other bottle. Fill the tank so it has the maximum fuel weight pressure against the petcock. Be sure its in the ON position and let it set over night at a minimum..or do the test when the weather says its gonna be crappy for a few days.
Object is to see if any fuel accumulates in any of the bottlles..and using two bottles will tell if the leak is via the vacuum tube OR via the fuel delivery line to the carbs. Get fuel in any one..replace the petcock. As many here that have tried rebuild kits..they RARELY are effective. Do NOT get any fuel in the bottlles the petcock is OK
