08 wr 250 will not run unless hot start is held in

I have an 08 wr250 that just started sputtering last week and progressively got worse. Now it will not even start unless it is kicked slow and the hot start is held in. As soon as the hot start is released or the throttle is touched the motor dies does anyone have any ideas

Did your fuel screw fall out?  The hot start leans out the fuel mixture, so if it only runs when its pulled in my first guess would be missing/miss adjusted fuel screw causing it to be too rich.

How's the air filter look?

I took the bowl off and the pilot jet just fell out back in now runs like champ thanks
