[Public-List] Manifold petcock Atomic 4

[Ronald Walker]

The engine is the old Atomic-4.Its my understanding that all Albergs were originally powered by them.I believe the petcock is brass and the manifold is some type of steel. As I said the threads are there, just flattened out. I'm going to try some J.B.Weld. Don't know what else to do.
