Thanks for the replies Joe, TM2C and Jerry.

The carburetor is a Rochester model "B", for my 216 Stovebolt engine.

Thread is 1/4-17 pipe for the inlet. I believe next size up is 1/2 pipe and I don't think there is enough material on the casting to support a threaded hole that big (would be nice though, allowing me to connect the fuel line without the brass adapter).

I don't believe Helicoil make a pipe thread repair kit (the threads are tapered, so it's hard to guess how that would work). I've heard mixed reviews on the Permatex kit, mostly about the material letting go if the fitting is tightened.

I'm kind of up against it, national VCCA meet is next week. Ain't that always the way.
