It's been some months since last reply.
Have you tried spraying starter fluid into the air box?
That should be a quick and easy thing to try.

Fuel line could be clogged, remove the fuel line before the carb, see if fuel comes out. Or could be fuel petcock not allowing fuel through.

Remove the sparkplug and screw in a compression tester.
With fully charged battery crank it and open throttle fully get some compression readings.
