I repaired the banjo bolt (in carb) threads using a 3/8ths x 24 heli coil set. The taped hole comes out to 11mm
which leaves plenty of metal for strength. Rethreaded the bolt to 3/8's and can now tighten it as needed. Leak
checked it and all is good. Just thought I would pass this along as you can save that carb.
