I have a 2000 Polaris Xplorer with the 250 two stroke motor
It does not want to start with the electric start, the motor cranks fast, the battery is good, and there is good spark when cranking. The engine starts perfect when using the pull cord, it even starts if I pull the cord slowly and starts with one pull. The engine idles smoothly once started. My wife says she needs the electric start to work.

My son’s 17 Alterra 500 just quit today. It was running fine the started stalling and bogging at half throttle. It finally stalled and will not start. The bike was won in a raffle last year. It had sat for a year before he won it. Has ridden it very little since. It has 180 km on it. We checked the plug spark seems strong disconnected the fuel line at the pump and the fuel pump is working well. Disconnected the injector and it is spraying fuel. Air filter is clean and there are no mouse nests in the air intake. Al fuses checked and good. Ideas?

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.

The title pretty much explains it all. When using the starter I can hear it spinning but not engaging the engine. The wheels also do not engage with the wheels when the clutch is out. The motor has compression if that helps.
I am new to engine work and repair and I bought this quad with the idea of fixing it up (not knowing the full extent of the damage). The previous owner said it ran but sat for a year (I don’t believe that for a second after opening it up) and had bought a few new plugs and a starter motor, none of which fixed the issue.
Any help would be greatly appreciated!
I have attached a few pics of what I think could be wrong.

I have a Chinese Hybird 250 or that's what I was told it was. I found 17 numbers on the frame. Will these numbers tell me exactly what it is that I have? (I know that its a 2006 from a plate on the front)
