Hi fellas,
Looking for information on the ideal main jets size at sea level for a FORD 94 carby on a stock 59A engine. I searched here but couldn't get a match.
Any suggestions would be appreciated
thanks
Dave

#50 or #51 was stock

51 is good for sea level, and I've had mine to 10,000 ft with no trouble also.

Thank you that's a big help. The highest "hill " around here is about 500 ft!

So how much of a change is required when an engine is bored oversize to 3 5/16"(with std 3 3/4 stroke)
Any other changes (jets , pump stroke etc.) required for a basic start point?

At first I tried 55's on my 265 8BA (+60, 4 inch stroke) and it was too rich. Went to 52's and they work fine, so I'd suggest trying the standard 51's first.

None, run em as you would on a 221 or 239.
