[CHRIS POTTER]

I agree with David, I have also had good luck with a Proform main body, but have heard of QC problems. I tried my son's 750 Speed Demon on my car, and it seemed to have a little more power, but the driveability isn' t as good. To be honest, however, I fine tuned my Holley, and I tried his carb out of the box. I couldn't get the Demon to idle down without kicking the gas at every stop. Tried extra springs, and there are no binds when the engine is off. It's not my carb, so I didn't get too involved, but it does the same thing on 3 similar engines, maybe their tech line would know why.
