Check the reed valves - hold them up to the light to see if they are sealing closed.
Did you clean the pilot jet in the carb? - it's opening is as small as a pin hole and easily clogs with bad gas.
Check the compression - may need a top end rebuild (cylinder, piston & rings)
2 stroke engines require rebuilds quite often.
If you don't remember the last time it was rebuilt - I think it's overdue.
