I have a 1988 Johnson 70 VRO 3 cylinder outboard. I bought it second hand and it had a slight misfire at about 2000 rpm.
I put it in for a service and said that it has a slight misfire. When I picked it up a month later I was told that it was all fine. I took it out on the water yestarday(6th May) and it was missing all over the place but ran quite well if you could get it to full throttle.
I tried another set of new plugs but still misses. Any suggestion on where to start on this?
I have not checked anything out yet as not had time. Visually, all looks good, no cracked coils etc.. Greatfull for any pointers here.
thanks.
