Thanks for your quick reply. Probably less than 50, no 20 miles. It had been surging ion park and neutral for that matter. Go back a bit-car sat for two years, the story of which I replay in my mind on Halloween Eve. I took the vehicle to a guy who rebuilt '67 and another Camaro, etc. Had them replace battery drain/flush fluids, new tires, new fuel pump, and a bunch of other stuff unrelated to engine. Noticed that engine was surging in park and neutral (2000-2500rpm). So had high Idle solenoid replaced. Stopped surging and idle was high 2000rpm, dropping to 900 in drive. Horrible clunk in gear though. Told replace/rebuild carb was solution. Replaced radiator, all water hoses, all vacuum hoses, rebuilt carb professionally, Intake manifold/gasket, higher thermostat, water pump, spark plugs, wires, ignition set. Drove awhile and while in garage, noticed that before turning off idle had dropped to 400rpm, choke light on, shaking and stop. Hard to restart. Had to go out of town for a week. Started up and battery DEAD. Jumped and took to shop. Diagnosis was misfire #*. Eventually told that they had smoke coming out of that exhaust valve/cylinder, etc. etc. There was strong smoke smell during the early process, but...I always noticed that choke started and would release with pressing pedal. they said that they did compression, but I didn't ask for numbers. They said only to replace defective vales, +gasket, machine head, etc. So th ere's the brief. What should I do now that we are waiting for the heads to come back?
