I presume this has been discussed before but I can't locate a thread. I see my throttle stop and lock screws are #8-36's on my Holley G carburetor. It looks like that is also the size used on some later Holleys. Has someone found a good source for these or are they re-tapping the arms with #8-32s? #8-36 is UNF which is pretty much obsolete now days. The Kingstons seem to be #8-32 and I have a bag full of those screws.
If this has been covered before perhaps someone can point me in that direction.
Thanks
Rich On this carb the stop screw was brass and the lock screw was steel.

Try fastenersclearinghouse.com. They list that size in several different types of screws.

Thanks John, I'll give them a look.

You might give Russ Potter a call.

Thanks Dan. I found a cache of brass ones on Ebay so I bought them and may have some extras.
I still am wondering if this has been a problem for others. I can't be the first to discover this.

New 8-36 screws arrived today. These are cad plated and will work nicely in my Holley Carbs. All of my Model G's used 8-36 and all but a couple of NH's have them. I believe the 2 with 8-32's were rethreaded. A 2 screw Holley also has 8-36 but with filister heads. So I believe 36tpi was standard for Holley and 32tpi was what Kingston used. No one has confirmed or disagreed with this yet.
To meet the minimum order I ordered more than I will need. If there is any interest I will put an ad for them in the classifieds to recover some of my investment. These are a bit longer: 3/8", 5/8" and 1".
The original locking screw was 5/16" and I have seen both 5/8" and 3/4" for the stop screw.
Let me know if interested.

The brass ones are one the way.
