Bought my coleman u400 from TSC last year, was running great. I live on a lake and use it almost daily to climb a pretty steep hill from my house down a path to the water. Last week was driving up the hill and it just quit. First thought was I'd run out of gas but it has almost a full tank of gas in it. Have tried to get it to restart and the lights come on and it tries to turn over but won't catch. Checked the battery and tried to jump it just in case but it's not that. Checked the starter and it's good. Can't find the spark plug to even check that. I called the local repair guy in town and he told me he doesn't work on Hisun since it's all shit and I'd be better off burning the damn thing so that's been no help. Would appreciate any other ideas.
