it does idle a bit but I mainly do small 5 minute sprints to next fish spot in the river.
It runs great on full throttle, idle is a little rough but OK.
I was interested in the black dripping oil stain out the 2 exhaust ports at rear of motor and in water when flushing in bucket
looks like an excess of oil in fuel mix but i know its at 50-1
I will try some low smoke oil and give it a flogging next time out
fuel air mix screw is an easy tune, screw in till starts to idle rough screw back out till idles rough screw back in 1 -1.5 turns, this is what I read online, happy to be correted
I will pull the plugs and see what they look like as well
I have a 2000 Johnson 9.9 spare as well if things go pear shape.
thanks for all the input gents
