Thanks for your help

I have an issue and I'm hoping that someone can help with a little Wisdom. I have a 2016 Massimo MSU500 UTV that blew a time chain while out riding. It has been torn down to replave the chain and Sprocket amount other things that will be renewed. The problem comes in with setting Top Dead Center on the motor. The Manuals all teel one to line up hash marks on the flywheel with a point on the side cover under what's referred to in several place as a manhole cover. Its a large headed cap/bolt that unscrews and allows you to view the edge of the flywheel. There are hash marks on the flywheel that your supposed to turn the crank until you get the proper alignment between a certain hash mark and a reference point on the Case. Problem is there is NO reference point on the case there. I also have another 2016 MSU500 and a 2014 Coleman 500. Not one of these machines have a reference mark of any kind in that location. (I have pictures if needed)
I know I can use the old pull the valve covers and rotate the crank and rely on getting the right point where Both Intake and Exhaust valves are closed at hopefully the correct point in the piston stroke. Is there any other reference point that could be used for this or is this the only thing left to use for finding TDC? Gotta Love documentation that doesn't match the equipment it's supposed to be for, any help would be greatly appreciated. Even if just to tell me that's about my only option.
Thanks to all who even take the time to read my rambling question.

Howdy Everyone,
New member looking forward to learning and sharing more about UTVs. I have a 2019 Coleman Outfitter with the Hisun 550 engine. Does anyone know what Code Scanner will work with it ?

Quick history:
Bought it about a month ago and when I test drove it, it ran good. Loaded it up and took it home. Owner said it had been sitting for a long time, but was "just serviced". It only has 500 miles on it total. Drove it around and found out the charging system wasnt working...so had to charge the battery once every week and a half or so. One day my daughter was driving it and it died. I couldnt get it to start again and I noticed there was no fuel in the filter...I first checked pulse/vacuum line to make sure it was sucking and it was. So I replaced the fuel pump with one I found local...which is for a large riding lawn mower...and it worked. Engine started and ran, but struggled at low speed immediately following running it at higher speed. It would bog when decelerating. I have also noticed now that it will backfire some on decell and die.
In the meantime, I went ahead and installed new stator and trigger coil assembly to get the charging system working again (that was an issue because it would not start at all after that...but eventually found that the trigger coil was wired backwards in the plug from the factory). I have also set valves, but I set them to .005 (intake) and .007 (exhaust)...per the manual. But what is weird is the manual states its mainly for the 700 series, but "can" be used on other models. On the front it says 500/600/700. I have noticed that the most common setting seems to be .005.
Anyways it still has the issue to me that seems like its running lean. Not full power now, struggles immediately running it faster, and will die and pop some on deceleration.
My main problem now is that it wont get to higher rpms as fast as it did when I first bought it. It struggles on deceleration after running near top speed.
Things I have done:
changed fuel pump
replaced stator / pickup coil
thoroughly cleaned carb (twice)
set valves to .005 and .007 (is .007 too loose for exhaust?)
anyways it seems to have a lean problem, and wondering if you have any suggestions on what to check.
Thanks
