Weird, sudden AFR issue Proform 750cfm!

Do you have the thin coated crush sealing washer/gasket installed "between" the screw and shooter, along with the gasket that goes between the shooter and body?
Yep. Tried a fiber gasket on the bottom that Mopowers sent me. I bought some Demon 190017 gaskets, gonna try those next. I have to walk away for now. Too pissed, and now it's storming, so I can't test drive any more today.
