What size carb. and needles and seats? As already said, fuel pressure and fuel delivery are not the same




825 Demon. Float levels are OK. .110 needle and seats. I cant see it being a needle and seat restriction issue, motor only makes maybe 425HP. Pressure is fine, at least at idle. 7 PSI at idle.
