    Default Carb Jetting Starting point ?

    Dominator 1050s on a very healthy 8/71 blown 555
    Traded my e85 carbs , going back to gasoline .....
    lost all my old data I had written down on old tune up , but that engine was 454ci and not near what this engine is
    IIRC those jets were 89 squared

    anyone out there on gas running something similar in a 555 / 565 ?...where are you jetted ?

    Put the carbs back to stock and start from there. If you want them done right, send them to AED.

    Factory jets with no power valves for gas is 95 squared. the factory jets on a 4150 series 1050 with primary power valve is 90 98 on E85. You probably were very lean with your'e previous set up! Now with that being said they make different 4500 series 1050cfm carburators the only real deciding factor is the list number on the carburator. Mark
