Subject: [Healeys] Helicoils in SU carbs

From: Linwood Rose <[email-masked]>

Who has used helicoils in their carb bodies so one doesn't have to put nuts on the back of the carbs when installing K&N or other air cleaners? Fiddling with the bolt head or nut from the back side of the carb is a pain. I believe I have read that some have used helicoils in the carb so solve this problem.

What size helicoil is used? In my case I am using HD6 carbs if that matters.

Thank you!

Lin
