Thanks for the reply. Idle AFR seems good to me and meets all your comments and if I back the screws out another full turn the AFR will go down to about 12.
I hadn't realized the idle circuit was playing a big part so long into the cruise region, I will have to put more effort into that area.
It also seems I still have a bit to learn on the terminology, from web diagrams I have, the idle air bleed and bypass holes are in the Carb Top by the metering rod area. They both use brass inserts and the bypass one sticks out about .060" from the casting. I also have the original TQ carb from this engine ('73 with a 2124 top) that hasn't been used for 20 years, and it has the same inserts.
I think my first step is to fix this hole and then see where I am. I would send a picture but couldn't get it to attach!
