Hey,
Does it have spark? if not it could quite possibly be the wiring harness. I had tons of electrical problems on mine and i replaced everything but nothing worked until i replaced the harness.
If it has spark then maybe check the compression and see if it has good compression. it also could be something in the carb. I would suggest cleaning out the jet in the carb becasue they get clogged quickly with twostrokes. If it still dosnt work then check and see there is being fuel being delivered to the carb.
If you need help with any of this, message me.
Hope this helps!
