I'm working on a Coleman UTV 400 that has a rough idle, owner has had it for about a year. When I say it has a rough idle, it doesn't have the continuous smooth running sound. At times you can hear it kinda skip, sputter, or like the RPM has fallen (RPM stay constant according to the gauge) It's not as bad as it was after I replaced the fuel filter and fuel injector (both are Chiki) not sure if that is a quality brand at this point. Checked the spark plug, it was a little foul, but not too bad. (Since the engine is still idling bad I'm going to replace that) Cleaned the throttle body making sure the carbon and soot has been removed, and the air-filter has been cleaned. New fuel is being used so it's not old or been standing. They did tell me that they were using non-ethanol fuel, not sure if that would be causing the issue. Next two things I can think of that maybe the issue is the O2 sensor or the valves need adjusting.
Thoughts and suggestions? Thanks in advance.

So I've got a Hisun 550 that I was doing some work on that required removing the CVT and it's housing. Upon attempting to reinstall the clutch, sheaves, etc, I found that the belt no longer fits - it's far too wide. None of the parts have been replaced, they're all OEM. Exactly the same parts as what I took off a few weeks ago.
To be more specific, my belt is 1.25in wide, but the gap between the clutch and the primary sheave is only 7/8in wide. I'll include a few photos to explain.
Has anyone ever experienced such a bizarre problem? Any help at all would be appreciated, I've been stuck on this for a month. I'm open to just about any suggestion.
