Do you have a smoke machine? If not, I would get a cheap one and search for vacuum leaks around the intake. I have one from amazon I use on my cars and stuff like this, works pretty good with baby oil. Amazon Link

Did you ever figure this buttoned up? Good video on clutch removal Hisun 550:

Do you have power at the fuel pump relay?...actually I see you posted that. I would start checking the wiring from the relay to the pump.

There are a couple of service manuals in the downloads section:

What year/model is this? How's the overall shape of the atv?

I’m with you on this, I like forests and public lands. A nice trail that’s scenic. I guess I’m getting older now.. used to like mud and going through water/snow for a more challenging ride.

Still using my snowsport ATV plow from 2009…We got nailed with almost a foot of snow in lower NY today!

They make them but they’re expensive!
