Problem: The ATV starts and runs at idle perfectly. But as soon as I open the throttle, the engine starts to slow down until it stops. On the attached video you can hear the sound of how it works: see video below
Prehistory: there is a Polaris Sportsman 500 1998, which for about 1.5 years stood in repair, including also replacing CDI with one taken from the same ATV. Finally, the vehicles were on wheels, traveled several kilometers and overheated - forgot to fill the antifreeze Came back home in small moves. The next trip started well, but after 10 km there was a feeling of a small drop in power (even as the vehicle got warm completely) but still drives. Next trip - the situation is repeated. The next test of ATV through time and a huge loss of power from the very beginning. The engine sneezes, does not want to go more than 5 mph.
What has been done: the carburetor has been replaced with a new one (inexpensive, $ 40), a new spark plug, a new ignition coil, the engine head has been removed, the piston is in good condition, valves were corrected - but the problem was definitely not in them.
Ignition control unit is suspected. Who faced similar? Please help in solving the problem.
Thanks in advance.

I was given a "Go-Kart" its an old Carter brothers dlx150 but the engine is not the same that came with this Kart. I am trying to ID it so i can look at getting some parts for it. the pictures attached are of the motor and the only ID marks on it. I am thinking its some sort of 200cc from the 1980's does anyone have a better Idea? I am really trying to get a rebuild kit for the carburetor. on the carburetor is Keihin 63 AA YKT
It's been a while since I posted. Fan trouble and the replacement I sourced on amazon is still working great on my 2005 Suzuki KQ700.
Unfortunately this year I lost my outdoor best friend. He's that go to guy for everything … the day run, may walleye opener, last minute hey my boat's at work get your a$$ over here with your rod and let's go kinda buddy. I bought the quad last year in March and with him gave it the once over and prepped it for fall hunting season, but cancer took him before we could enjoy this new aspect of outdoor life. We planned an October trip into the bush with our quads guns and tent trailer. It never happened. A tribute to our fallen and lost.... But in their memory take the opportunity to grasp every minute of the outdoors you can, life is short... you can sleep at the end...
I've curious what everyone has been doing to prep for the spring season. I mounted my battery and the quad started up straight and easy, just powered it up once or twice to juice the injectors and it fired up after a couple of seconds. I let it run, confirmed fan started, checked charge voltage. all good. I did all my oils in the fall to make sure no water was present anywhere so skipped that this spring.
So what have I done over the winter to prep for quadding? I've been researching. This year I am going to cross over quading with brook trout fishing. So I have been pouring over my old maps from my youth, google maps... looking for those faint markings of trails I can't travel in my F150 (well not yet, paint still looks pretty good ).
picking up atv tomorrow, guys says motor is locked up. he thinks, anyway has been sitting for more than three years. Please understand i have not touched it yet but if his description is accurate im looking for suggestions on freeing it up before having to tear it down. I'm hoping to get some great info from the pros on Quadcrazy.
So need some recommended maintenance I should do with my 1998 Foreman 450ES. I didn't get much info as to what had been done so what's the things I should perform to start me from square one? I'm not a mechanical genius but can do the basics. I did adjust the toe today so I'm not a nooby.
