I am electronically challenged - and installing a Tiny Tach on my new Etec 25hp. In the pic below, can I loosen the bolt on the assembly to the left of the spark plug and ground to that (since it's the only metal object within reach of the factory-installed ground lead)? [/img] Also, does anyone know what degree setting I would use? I'm sure I can figure it out by just changing the settings until a reasonable idle is displayed, but if someone knows it would be easier to set it while in my garage. Thanks as always.
