Tach isn't working now. it worked a month or so ago when I started it up.... Now it's not working at all.. tapped on it and jiggled the wiring and such.... There was a few mice in the trailer it looks like but no obvious signs of chewing... Anyone have a wiring diagram or able to point me in the right direction for troubleshooting? Old thread recommended running a wire from the CDI but not sure what wire it is. Blue if I had to guess... Thanks!!
Oh, mice was my first thought.
i know a rusty flywheel messes up the ignition timing.
I've seen this before, it's because your battery is too dead, or because there is no battery at all hooked up.
AGM Battery with a full charge, cranks right up and runs fine ....
