Holly Carbs

Can anyone tell me how I find the type of Holly carb I have? Where are the numbers located on the carb.

Thanks
Frank

On the throat of the front two barrels are stamped numbers. Those give you the design of the carb and version, e.g. 3310-2.

Post up a pic and "these guys" will be on it like a duck on a Junebug - - :3dSMILE:
