Suitable for carburetors that use gasoline as a fuel (not E-85). Contains four each of main fuel jets 62, 64, 66, 68, 70 and 72 for quick global adjustment of the fuel curve.  Four each of the air bleed 10-32 jets .024, .028, .032, .035, .040, .055, .060, .065,.070 and .075 allow quick small changes to the main, intermediate, and idle circuits.

Finally, .033, .035, and .040 accel pump squirters change the duration of accel pump fuel from leaner and longer to a quick discharge.\u003c\/p\u003e\u003cp\u003eGenuine Edelbrock.
