I have a 1966 coupe which I am restoring. I just replaced the water pump, added a new 4-row aluminum radiator and new thermostat. The problem is overheating when I turn on the A/C? I would like to drive it, but it still has the same problem, and now I cannot get it to idle. Starts fine, runs as long as propted, but dies @ idle.Could be clogged fuel line, trash in filter, loss needle in carb, WHAT???Please HelpAn old novice
what carb is it?try adjusting fuel mix screws.might be power valve leaking slightly.does it only idle bad when hot?what brand of rad?fixed fan or clutch?how many blades?what is idle timing?what is max timing?what thermostat rating? you need a 192.how hot is your weather?do you have a factory shroud?how hot does it get in traffic?how hot on fwy?did you check with infra red?
