    Can anyone tell me about the size of the Idle feed restrictors? Are they different size's or all the same? I bought 2 blocks but came without them and now have to buy the kit or kits..6 different ones listed? .029 to .039

    It seems odd that your blocks didn't have them. I would call Proform and ask why, because mine came with them.

    For some reason the carb keeps dumping fuel..proform and Quickfuel tech can't even figure this out?

    The only thing that has worked this weekend is that we put metering blocks on from a 950!!

    Hmmm...that doesn't sound good. So how did it run with the other blocks?
