Plumbers tape is either impregnated cloth or teflon. Teflon tape is not recommended for fuel lines as bits of it can get into fuel pump valves, carb needles/seats or jets. Its use often voids warrantees

Fred, did you perhaps miss JW's idea? As I read it he is proposing to use the tape as a release agent in using JB Weld to form repaired threads and not as a final part of the assembly.

Do you have a part number for the body? I have a few laying around maybe one will fit.

Thanks, all. I got it to stop leaking temporarily with a new O-ring and a tiny bit of teflon tape on the threads. I can't tighten it very much as it starts to squeeze out the O-ring, but I got it fairly snug. The threads are still sufficient- the cross-threading simply doesn't allow the plug to sit squarely on the carb, and the fiber gasket will not seal.
Wesley, I'll look to see if I can find a number- I think the only permanent fix will be to replace the top. Thanks!

I've not worked on one of these carbs, but - unless this is a pipe thread (which I doubt) - the threads for that plug were never intended to form a seal. Rather they help provide clamping force for a gasket - likely of fibre material, originally.
Fuel filters for carbs in later years (60s-70s+) slipped into a bore in the carburetor air horn and were retained with an inlet nut that was sealed to the air horn casting with a coated, but thin, metal gasket or (later) a thin nylon gasket, which likely does not require as much clamping force, and won't squeeze out like an o-ring. You might wanna check with an old-timey parts store (not these modern, mass-market messes) to see if they have anything in this regard that's close to the diameter needed. While I've seen JB Weld used to effectively seal welch plugs, I'm not sure what you'd do if that threaded plug ever had to come back out.
