I am new to this forum, so I hope that I am not out of place. Daughter and son-in-law just bought a Cub Cadet Volunteer UTV (2008). To push snow on their driveway (they just moved to the country). I am helping them because I know a little more than Jason does. First problem, it was 18 degrees outside and it will not start. It has a Kohler engine with fuel injection. After we put it in the garage and warmed it up it started. Then it grinds gears when trying to put it in gear. I think the engine is running too fast. We unscrewed the idle screw and it lowers the rpm but does no stay at low RPM. Thank you for any advice.
