I have a 7042910 which was rebuilt by the carb shop when they were in Ontario Ca. Throttle shaft has been rebushed surfaces machined yada yada. I am trying to retain the 73 jets and 44B rods. This carb is a large main air bleed carb. I am building it for my ZZ3 motor. I have bushed the main air bleeds down to .068 from .115 in the main body and the air horn. The accelerator pump holes are .075. Do I need to bush them down as well to geet to .026 or .028? I am trying to follow recipe number one.
