There's probably a really simple answer, but I haven't been able to find it by searching, so I ask:
I'm rebuilding a 1968 CL90 and need to remove the fuel petcock from the tank for cleaning and refinishing. There are only three screws or nuts externally: two screws holding the lever on, and one hex on the bowl. When I remove the bowl there are no new screws exposed. I tried gently rotating the entire petcock to see if it unscrewed from the tank, but it didn't budge and I didn't want to break anything. Can anyone tell me how it is removed?
