Holly Carb
Can anyone tell me how to tell what kind of carb i have, I know its too big and i think its like a 750 double pumper but is there any where on the carb were it would have a model number? I need to get rid of it and get a 600.

If you open the throttle all the way with the engine off, do the secondaries open? If so it's a double pump. There will also be an accel. pump on the rear bowl. Otherwise the secondaries will be opened by a vacuum diaphragm on the pass. side of the carb. The model number will help more, but this info may help narrow it down.
