Quincy Welding used a custom made reamer for B&D carbs and A&C were not reamed. As I recall, John is correct on the size.

I have to think if you have carbs with widely varying I.D.'s, they may have been worked on by someone other than Q.W.

What's that I just heard? Ray Rodda just gave Santa and Rudolph "5 minutes to the 3"!

Merry Christmas everyone!!!
