I have a 1987 Stellar CXL with the 2.0l engine, all stock. On the highway, it seems to run fine and I get about 30 mpg but in the city, it is cheeper to run my old dodge ram! There is only 75 000k on it, new plugs, cap, rotor. Even tried a different carb with a manual choke but didnt make much difference, still only got about 10-12 but it didnt take 5 minutes waiting for the choke to open so it would idle down. I have checked the timing and adjusted the valves but no change. The only other symptom is the odd smell of gas (no fuel leaks) and the idle will not set below about 1100 rpm. I am running out of ideas and hate to get rid of it, with only 75k it is barely broke in and it always starts no matter what the weather. Any suggestions? All I have left is the vacuum switch for the fuel shut off solenoid and I dont know when it should go off. Thanx.
