Thanks
I have the Pro-Form 1050 annular body now with Quick Fuel blocks, bowls, and baseplate. It runs very well right now so that's why I hesitate to change the blocks but I guess I will have to completely change my tune anyway with the new fuel.
Maybe when I bolt the new blocks on my A/F ratio will be dead on shruggy
