I have had my 2014 leftover for just 2 weeks. Seems like when I use it to plow for a few hours, it wont idle. I can normally smell a strange odor, and I have to feather the throttle peddle to keep it running. Its been back to the shop 2 times in the past week or so, and they claim it runs fine with them. I told them it does it when I use it for approx 1.5-2 hours. According to the hour meter, they used the machine for about .7 hours,,, so of course it didnt act up on them. I think its a dirty carb, but they arent willing to tear it apart to clean it.
Help
