Re: Can not get this 18 running right.

quote wiscoboater:

I used an open air spark tester. It has a plug end on one end and an alligator clip on the other. it can be adjusted by screwing it in or out to change the gap between the two points. I checked it at 1/8 inch and had blue spark. I will try it at 1/4 see how it looks. That and I’ll borrow a boat from a friend and try it under load. I just won’t wander far from the dock.

Thank you to both of you, Wiscoboater

P.S.
I was running it in a 55 gal. drum with a fan blowing away the exhaust smoke. I did not try it in gear, only in neutral. Thank you for your patience with us rookies Frank. I’m learning a little every day about these things. The help from this site is truly better then any manual printed.

Well ok, there is your answer. Revving it up in neutral. That is causing your runaway. Also why you can’t adjust it. Let us know how it works out on the boat.
