Rough running Evinrude V90

[Green Lantern]

Try this tester (open air adjustable -- and cheap at an auto parts store). Start at about a half inch or a bit more, and dial back if the spark intensity is uneven: View attachment 345543

I will look for it at the store. I feel like my tester wasn't making the best connection. It's running pretty good now. Just has a flat spot as it revs, maybe between 1500 and 3000 rpm.

I cleaned them out something fierce.
