I have a sumitomo sh120, Its been running great. Today while traveling across the site, it slipped of a small rock causing it to bounce or jolt a little. It immediately shut down like you turned it off, now it turns over fine but wont even attempt to start. Any ideas where to start, it seemed to be electrical the way it shut down so fast.
Sorry for wasting your time with this post guys, I found the problem. The throttle cable broke, nothing electrical at all.
