I ran 2 Quickfuel 750's on a tunnel ram and they were the best carbs I've ever used. All adjustments are solid, no play in them, set the idle and everything and never have to adjust it again. Also LOVED the big glass sight windows in the bowls, I could see the bowls fill to proper level from the drivers seat when the hood was up.
