I have a stripped hole on my holley, for the squirter screw. What thread is this supposed to be so I can get the right heli-coil for it?

Sweet info Keg! I did the same damn thing with the used 4779 main body I bought off eBay... the threads were dirty and when I threaded the screw in it was snug, but I figured it was cleaning threads... well it was actually removing them! I lucked out in that I didn't go TOO deep so there's about 3/4 turn of a thread holding my front squirter on right now... maybe I'll try the repair method mentioned in that Hardcore50 thread next time I tear it apart.

I found a company, kind of rare, called 'recoil' they carry the 12-28. Im gonna swing by my local kragens tomorrow, se what I can find. If I cant find a 12-28 recoil or helicoil or something, I'll get the 12-24 and my drills out!

No luck finding 12-14 or 12-28. I ended up getting M6 - 1.0, and a few screws for that as well. Tomorrow I am gonna drill out the screws and see how things go.

Wont you need to be careful? The fuel flow to the squirter is up the side of the screw.You might have to look into hollow screws.

I made some hollow screws

I had a high flow squirter screw, so I drilled the new screws to look just like it. Now I have a squirter that is held in nicely, with room for fuel to flow. Next week I will be putting this carb on so we will see how it works.
