Re: Can not get this 18 running right.

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.
