i have a 1978 Johnson 85hp motor that has a slight hickup/misfire while at idle speed, but I can throttle up and while driving it will never show itself, but once it's back down to the low rpms of idling it has a hickup where it's a momentary non fire or mis-fire. Caused it to stall once on me today. Any ideas on what it could be?
I was thinking maybe the magneto is getting weak?
I just put new spark plugs in it thinking that was the problem but it wasn't.
