Hi guys..new here. So I just bought this car and gave it a good tune up but it still falls on it's face until warm and blows alot of black smoke (fuel). Also the clutch is probably not much longer for this world, how bad a job is that to replace? Also the heater switch doesn't work, is this common? Anyone know a year range that would apply to the switch so that I can track one down at a junkyard?
