Review on Performance Street Carburetor: Quick Fuel Technology SS-750, Mechanical Secondary, 750 CFM by Tony Doan

I would give Fast Fuel no stars if I could, their carburetors are terrible and suffer from poor quality control. I've had 4 clients buying their stuff and having nightmares trying to get it to work properly. I replaced them all with AED Holley carbs and the difference is day and night. I have 4 QFs that got hit by a 650 E-85 carb they drilled into the side of the booster, a Slayer 750 that idles so rich you think it's a top fueler. I have an 850 Black Diamond QF carb that flooded the rear bowl all the time, found the float hanging on the jet extensions, pulled them out but still had problems so I replaced the float with a good old brass Holley, no more flooding. I called back then in the past and QF didn't help at all (people said BG had bad carbs), stay away from QF, there are better things out there. I restore these items daily in my shop and now I have a huge box of QF parts, my Holley box is almost empty, what does that tell you?
