This is a follow-up post from my previous ones regarding my leaking carburetor.
Bob Kachergius at Uni Tech Management Systems produced a beautifully overhauled carburetor for me. Installed it a month ago and several test flights have been flawless. You may reach him at 708 – 267 – 7111.

Thanks much. Bob has my carburetor as we speak.

I wish to accept your offer of examining your hub, and agree to your conditions. Please advise with spe...

Al, Paul, I really appreciate your help. Some followup questions? Who makes the aluminum bronze inserts? How snug do they need to be when screwed into the cylinder? Obviously the dowel pin has to line up with a groove in the insert. Do you use Lock-Tite on the threads? You referred to the Continenta...

Thank you Paul.
Jim

Thanks Al
