Lots of folks like the Carter type YF better than the Rochester B.
Carter suggested the 2100s with manual choke; or the 2101s with hot air automatic choke for the 1954 235 CID engine.

Good carburetion is fuelish hot air The most expensive carburetor is the wrong one you attempt to modify. If you truly believe "one size fits all," try walking a mile in your spouse's shoes! The Carburetor Shop
One other comment, do you everything you can to make sure there isn’t something else going on besides a bad carburetor. There are many threads here that suggest making sure everything else is correct before blaming the carb, such as timing, coil, points, and the number one culprit these days...... old stale gasoline!! Two or three years ago I learned that lesson. After blaming the carburetor for all my problems I saw them all go away after filling the tank with fresh gas. It ran like a champ after that. We have 10-15% ethanol in our fuel here in the U.S. Don’t know if you also have ethanol in your fuel in France, but if you do double check to make sure it’s not over 30 days old. If it is then it will make your truck run poorly. Change it out for fresh gas!
