Thanks Warren.

Larry Renger does not have an answer either but he said he would try to figure it out.

Did this ever get figured out as to what the thread pitch is for the 020 venturi? I have a custom Pee Wee I am building and need to thread an aluminum tube for the TD 020 venturi.

11/64-40 will do the trick!

Where does one find this tap??? Pure unobtanium!

I find reference to Singer sewing machine tap as they used some odd thread pitch and size.

Yes, it is a custom made tool for sure. I think Singer used them way back.

I could check on a tooling price next week, but it won't be too cheap.

Not a bad price if it is what they say and is of good quality. I think 80 Yuan is something like $14.

I'd send them an email first before ordering, if you are able to. If you don't get anywhere with that I can check from my end.

I may have found a source in the states for the 11/64-40 tap. I am to get a price on Monday. Depending on price are any of you interested in this tap size?

Sounds good Jason. Shoot me an email, and if pricing makes sense, sure!
