Holley G tap size

Post by greenacres36 » Fri Apr 23, 2021 9:19 pm

I’ve searched everywhere. I need to know what the thread is on the Holley G mixture adjust needle is. I need to buy / make a tap to clean the threads in the housing.


Thanks,

Brian

Ace hardware has a good selection of taps. The larger stores do anyway.

That is an odd size ,i don't think you will find it at Ace, try Drills and Cutters .com they seem to have everything and reasonable prices.

Both McMaster and Amazon sell 1/4-32 taps. Local machine shop suppliers might have them, too.

I found one on Amazon. Amazing what you can find there. Not just books anymore. At least it wasn’t one of Fords oddball sizes like 13/32 - 16.
