For context recently got my first classic car. A 1979 Trans Am. And have been slowly fixing it over time. New motor mounts, brakes, fuel lines, wiring, etc etc.
Just did the exhaust and is now less restrictive. And the car was running pretty well but now it bogs, pops, backfires, and stumbles. Is that a lean condition? I readjusted the carb and gave the idle mixtures screws more fuel but it seemed to do nothing. Float bowls are adjusted right.
Do I need to up the jet sizes? Also getting good fuel pressure 6.5psi.
Obviously carburetors are like black voodoo magic and have a basic understanding.
