    Purchased a new American Sportsworks ATV at TSC last spring. Didnt use it much and it slowly became harder and harder start. It is the fuel injected ECH440 engine. My mechanic friend says it starts right up without the air filter on but refuses to start when it is on. Any ideas?

    Shoot Kohler an e-mail with the engine model and spec number(silver sticker on side of engine). I believe they had issues with the fuel pump and filter on ech440 engines. Any time I have contacted Kohler they have been helpful.

    My dealer called me with the machines it applied to...and then they came to us and swapped them out. I think they were around 2014 but I've slept since then.
    They would have been either 34HP or 38HP machines if that matters.
