2-stroke engines use an oil and gas fuel mix. Diesel is oil, but there was too much of it to make a proper mix. Diesel does not spark ignite. After you rinse it all out of the gas tank and fuel lines and carburetor, start the engine with gas and starting spray to un-foul the cylinder- run less than a minute. Put in the right amount of 2-stroke oil and drive. There are no valves to ruin in a 2-stroke. If the engine ran at all on the diesel, I bet it died before any damage occurred.

I drained all the fuel and all the lines took plug out and pulled it over 100 times and fuel was spraying out the spark plug hole. I did it til the fuel stopped coming out the hole, then I put the plug back in and tried to start it and got nothing. I pulled the plug back out and it appeared to be completely dry.

If she got it to run a little bit before the diesel got in the engine then yes it is fried. The engine will need to be taken apart and looked at. Most likely the cylinders are damaged and so are the values. My guess is you just lost a 4 wheeler.

Clean out the whole fuel system fully and it should be fine
