67 slant with 1920 holley dies when engine heats up and choke opens.

My slant is running great with the old,original carb I refurbished myself.I wanted to see if anything was amiss with the remanufactured one I have,which ran on this slant,but was bogging down on acceleration.Low and behold,I have a 50 jet size in it,and the Holley list #4165 states it is a 1969 carb,and should have a 56 for auto,57 for manual trans.If the jet numbers are linear,6 divided by 56 is almost an 11% loss.Do you think that could cause bogging?
