SOURCE: yz 250 wont kickstart
You obviously look after your machine and very sensible when laying up, however as you are probably aware 2 strokes rely heavily on compression, A. to produce excellent combustion and B. to draw fuel into the chamber. So when you try kick starting you can't get enough revolutions to draw the correct amount of fuel into the cylinder, where as you push start you constantly turn over the engine increasing compression slightly and bingo it fires.
Can you remember how when kick starting it before this problem the feel on resistance when kicking over? has it now become a lot easier? if so you possibly have worn or broken compression piston rings.
A compression test will reveal this, I hope this sorts your query?

pull the sparkplug[s] spray some PB Blaster inside, then let it set like that for a few days....then try to kick syart without having the ignition on...if it starts turning....then replace fresh plugs and you'll probably needs to spray some ETHER [ starting fluid ] in the intake to compensate for the oil you sprayed inside

Don't know if it is water cooled or not, but it sounds like you may have a problem with oil or water getting into the combustion chamber and fouling the spark plugs. Kicking doesn't produce the amount of rpm that you need to fire up a weakly firing plug. I'd check the plugs condition first and replace if needed, and then figure out why its smoking.

Testimonial: "good advice, found out oil was getting into the chamber through the main crank seals thanks "
Sounds like low compression. Do a compression test,and it should have at least 90psi,..if not,its time to rebuild the top end..(piston,rings,bore)...pretty common for two strokes.

Testimonial: "Cheers pal, I'm gonna have a look at it on Sunday, but it does still run when i bump start it, it has lost a little bit of compression though, but when it runs it still goes into power band and that..."
