I would start at
68 jets in the primary 72 in the seondary ( 18 sound sligh for vacumn and usually the power valve is half the vacumn .. was it at the carb ..if so its 1/2) 31 squirter is fine I ave never changed pump cams in my life from stock ..I would make sure the play in the accelaertor pump lever jiggles about .015, I would use std 28cc accelerator pumps NOT 50cc should work.
