63 pri jet

(1/1)

77cruiser:
Never seen one that small. Carb no. 17057213 single AB 40B rod.

Cliff Ruggles:
Pretty "oddball" carb, early design with single main airbleeds, divorced choke.  We free up the APT screw in the baseplate, open up the MAB slightly and install a .070" main jets with the 43B metering rods.....Cliff

77cruiser:
Thanks Cliff!

Where would you go with MAB size to run off the 63 jet/no rods, might do another oval track one?

I haven't measured the MAB exactly but it's smaller than .062, I'm thinking if I go to about .065 - .07.
