My '55 T-Bird came with an assortment of parts. Two teapot carbs and an Edelbrock 1406 600CFM (AFB copy)carb which was on the car along with the original distributor still being used.

I have installed a later 292 distributor, Pertronix with new coil, etc. and it is running fine now, except it is running too rich.

So, can anyone tell me what the CFM on the original teapot is?

I am deciding whether to take it to someone who can jet it properly, or change out the carb to a smaller one. I cannot see why this basically stock engine needs 600 CFM.

Can anyone more carb conscious than me suggest what needles and jetting would be a good baseline for my engine?

Advice requested and appreciated

PS: Should have mentioned...not a teapot fan. It will not be going back on the car.
