2 stroke?
If so, do a compression test.

 

has good compression

 

Hows the plug color? A jetting problem?
If compression is fine, it's fuel or electrical.
It sounds like a timing issue, but unless you've messed with that it should be fine. Maybe a bad CDI/coil. A ohm test can check that. Sorry I don't have the ohm specs.

 

Sound like dirty carb and stopped up jets. Disassemble carb and clean. Make sure
main and pilot jets are not obstructed and you can see through them. E-ton makes a manual choke kit that makes starting a breeze and gets rid of pesky electric choke. I just installed one today on customers old Lightning 50 E-ton. If your not getting proper fuel delivery your engine will be lean and run hot.
