12-24 Heli-coil kit at NAPA BK 7703043. Heli-coil HC5521-1 on the bag. I might have one around here.
If the results don't match the theory, change the theory.

I have drilled and tapped carb bodies so I could use 1/4" bolts. Using 1/4" bolts also allowed me to find ones that were slightly longer so that there are more threads engaged. It seems like the holes only had to be 1/64" or 1/32" bigger.
