I don't think the pump shot would make it idle like crap, it idle has a miss and sputter out of the exhaust, and smells rich, I have to backout the mixture screws to 4 turns so it'll idle with less sputtering amd misses.
I tried carb cleaner around the base, all vac connections and the ones with plugs in them. no idle change.
Just a lot of sputtering, won't even think of road testing, but acceleration has no lag.
I am just puzzled
