From looking at the catalogues, I'm guessing this is for a Kingston L-4. Is that right? How about the little copper washer? What is that for?
This Holley G part has to be removed to get the venturi out.
This attaches to it.
The problem is that sometimes it gets so mangled in removal that it has to be drilled out. Is it available anywhere, or will I have to make it myself?
Try the blue wrench. The venturi looks shot anyway.
Steve it's time for some heat and an easy-out since it looks like the slots are gone. Play the flame on the brass as much as possible then pour a little water on the cast iron to shrink it before using the easy-out. the other option is if it's not shot leave it in place.
I'd use heat if it was a cast iron body (1919-1920), but this is one of the brass ones (1915-1918). It's a nice one, and I don't want to wreck it. That piece has to come out to remove the venturi, or more important, put a new venturi in. You can see in the picture that the old one is going to pieces. I can drill the hole bigger and use an easy-out, but I'd like to find a source for a replacement of the drilled-out piece. In fact, it would be nice if there were a lot more G parts available. You can buy a new almost anything for an NH, but not for a G.
Steve,
I had the same problem some time ago.
I soak it in vinegar for 24 hours and took a torq key (6 points star) that just didn't go in the hole. Tap it in with a hammer and the screw came out. After I clean the burps and used it again.
The carburetor is working great.
Good luck

I make that part, also the the idle tube, but not the cap nut, because it seldom gets ruined. I can drop one in the mail if you like. ---Len
