I have some drivability problems with my 83 Pontiac 6000 2.8 - which I
think is caused by a bad carb float. The engine will stumble when driving
around corners, backing-up and when climbing a steep grade. I've also
changed the MC solenoid and checked the ignition timing, plug wires, vacuum
lines, fuel and air filters and EGR. Any advice on rebuilding or replacing
the float in this carb would be appreciated.
