Are you loosing transmission gear oil? I seem to remember an older bike I had with a crank seal issue. Gummed up plug is usually only 2 things:
1) Carb too rich. Check jetting or sticky float needle valve that will dump fuel into the intake manifold.
2) Too much oil (check mixture ratio or crank seals that is mixing crankcase oil with the fuel mixture). Either of these two oil issues should produce a massive amount of tailpipe smoking and a noticable drop in power.

SOURCE: power valve position and installation for yz 125

The proper adjustment is achieved when the notch in the actuator lines up with the pin hole in the cylinder casting.

I have a yz 250 2 stroke that blows the compresion out the power valve what wrong?

Seems to me you have a burned valve. Have a compression test performed on your engine for verification.
