Weird, sudden AFR issue Proform 750cfm!

Yes. It's been there the whole time.
I did look for a crack, and couldn't find one.

Rebuilt my other Proform this morning. I wanted to, anyway. About to go swap it out in a bit, took a break to go see a car show.

Tony Defeo suggested checking distributor advance to see if it's hanging up, or maybe a weak coil, since I've been through the carb so many times already.
So, if the other carb does the same, I guess that will be next.
