i have a 1990 mazda mx5 1.6i and it appears to be running rich as i am getting a lot of white smoke out of the exhaust when i accelerate, the power is also down slightly, i did feel it may be the head gasket gone however i am not using water or oil and they are not congeling together so this makes me think it may be fuel, also the smoke does not smell like burnt oil it smells like unburnt fuel mixture? i have change the ignition coil regulator and the spark plugs so i know all four pots are fireing, any suggestions?
