my friend bought this holley carb used and it was all messed up. i rebuilt it and it when i got it all back together and on the car i noticed that the primary side wasent squirting fuel. so after looking at it i see that the accelerator pump cam on the primary side was missing. so i get one from another carb put it on and its like its not big enough. my question is do the primary and secondary accelerator pump cams have to be the same? or is the one i have on the primary side just not the right one? thanks in advance
