    JET Recommendation

    I believe the carb number is 4575.



    I blocked the power valves and added 90 jets squared. It has 50cc pumps front and rear. Any opinions?

    Is that a Dominator with a choke?

    on Holley's website they have a list that shows what jets come stock in each carb....I would find out what they had new and start there.

    Yea it was an old one! The choke was removed and I made 2 passes with it..it ran 1mph quicker than my old carb but seemed to get hot quick so I installed my little carb back on..before I started it up I pulled one of the plugs and it was dead lean looked as white as they came new...so 90 jets were too small!! I need a good dominator to try. 8)

    I'm running 92 square on my older 1050 dominator which is atop my 13 to 1 compression 496 BBC Runs great and pretty consistent but I think it's still alittle fat. Whats your timing at? Cp
