Check the fuel filter? I just had a similar problem with my '50........Mark

Strip down the carb and blow out all the holes with at least 100 PSI

well I changed the carb for a new one and cleaned the other one...no change

See if the spark goes to yellow /weak at the half rev limit, pull a plug wire hold it against the head nut ,or shove a screwdriver up the lead end

Do you have a modern fuel filter that might be plugged up?

 

[pistonburner]

no fuel filter

Had a simular problem with a 1950 (other make) found there was rust flakes in the fuel tank that collect around the outlet. would stop an the street and restart after the rust pieces settled away from the outlet. Cleaned and coated the inside of the tank, problem solved.
