This all started when I was driving after a walk on the trail my car was hot and not even a couple minutes later I pulled up to a red light and the car died I tried to start it with no luck. The car would start but run poorly and wouldn’t idle also white smoke would come out of the carb. I got a mechanic to look at it and we replaced the coil, ignition control unit, ignition wires, distributor, carburetor, fuel filter, put a pressure regulator on and the car runs but struggles at times. I had to change the oil cause it dumped about 2 quarts of fuel into the oil from us trying to start it. We timed the car but it still won’t run right no matter if we advance or retard the timing. Would appreciate some help thanks.
