Are helicoil inserts available in ME thread ? I have some Amal carburetor tops to repair 7/32x40 tpi. If not available I will make brass inserts and Loctite in position, my searches so far have not found ME inserts.

Never say never … but I really doubt if such items exist. sad

#4-40 UNC is common though … so it’s not the fine pitch that’s the problem

Thanks Michael, I doubt there would be a market for them. Brass inserts will do the job.

Can you open up to 1/4*40 and then make some stepped studs

The thread is 7/32x40 for the cable adjuster so 1/4x40 may not give enough wall section for thread depth. I will look at 7mm or 9/32" depending on which taps and dies I have. Thanks for the input.
