Well the advance unit might be a contributing situation but I would not think it is the full story. Let other voice in here.

made up my mind. after trying to get my 1978 engine to start and run smoothly.i have all ways had trouble with this.
i have decided to fit a 1975 engine i have. it has not been run for app 15 years so today i got it running put on my carbs from the 78 fuel line from can as tank all rusty charged battery. hit the button and she fired into life nice and smooth even tickover responded to the throttle. it even started by the kick start. so its going in the 1978
