Greetings,
Does anyone know the thread size for the vacuum advance fitting on the front H6 carb on an early TR3?
Thanks in advance,
 
I don't, but just for clarity, do you mean the threads where it goes into the alloy carb body, or where the compression nut screws onto the fitting? I believe the latter is standard 1/8" compression nut threads (whatever those are). Years ago I tried to identify the other threads without success.
 
Randall,
Either would work, I can either plug the hole or cap the fitting.
Jim
