Thanx lunaticfringe. I agree The front cylinder is cold, and plug smell of yes it must be something going on at the front cylinder because that fuel is not being used or combusted i take it. When i remove that plug to test for spark it wanted to idle as good as ever when the plug is outside, sounding abnormal off course. I have tested the resistance of the coil and its within spec. Can it be a leak somewhere with regards to air pressure?
