So I have this old Plymouth see,, and for the last couple years, it just runs like crap. Starts great, idles fine, runs good at WOT, or anything over about 1500 RPM. Around town it stumbles terrible leaving stop signs, or when accelerating after turning a corner. It has an 800 Edelbrock on it that is about 5 years old. (Reman from Edlebrock). Ran fine for the first 3 years or so. Took the air horn off, thinking I'd see a bunch of crud in the carb. Not so. Reset the float levels and reassembled, no change.
Heres the particulars.
