Petcock Leak, but not in the usual manner.
Leak at the two washers between the petcock and the tank. There's two washers because without two, the valve isn't facing the outside. I.e. the lever is facing inside, under the tank.
Apparently the second washer wasn't gasoline proof, and started leaking (took a year+). I could go get another washer, perhaps a teflon one, but I'm looking for a better answer.
Bike is a 1965 Gilera, and the petcock is NOS for Bultaco.
