[Healeys] Helicoils in SU carbs

Lin,

On my BJ7, I simply ran a tap thru the hole to create threads in the body.
I measured the original hole size with a drill until I found one that would
not pass thru.  One fraction size larger worked for me.  Then I used 2
bolts on each carb that matched the tap size.

Keep it simple.

66 BJ8
