Hi,
I have a 1250 alky dominator on a 1000 horse 565.
It has .040 idle .020 high speed and 200 main jets.
I’m have trouble building heat and it’s using fuel like crazy. This past weekend the temperature cooled and is seems to be way lean down the track. I replaced floats and kneedle and seats. I’m not sure if the lean is a fuel delivery or if it’s all in the carb.
Thanks,
Billy

If its building heat too fast at an idle, its lean at an idle.  Reduce you idle air bleeds to .028 and check the effect.   AS far as wide open down the track goes, if its our carb, whats our 5 digit carb number?
