Thanx lunaticfringe. I agree The front cylinder is cold, and plug smell of fuel...so 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?
