Hey guys, I stopped by my local Evinrude/Johnson outboard mechanics shop today trying to get some free advice. (He told me he was sold out.) Anyways he was testing for fire on a 2 clylinder and he had theses little sparktester lookin things that fit over the plugs and then clamped to the block on a bolt head or whatever. You could observe all the plugs while someone spun the motor. I asked where I could get some of them and he got all mysterious and inscrutable and such. What are those things called and where do you get em....Dave
