Never had that before. When I start engine it won't start without gas, if I let the gas engine drop rpm and die , after I work the engine little bit its all fine. Any suggestion would be nice. BTW yy250t engine.

Sounds like the carb just needs a little adjustment due to Weather change.
If the temps have dropped the motor needs a little more gas so try adjusting the Fuel Ratio Mixture screw, 1/4 turns at a time COUNTER CLOCKWISE.
In cooler weather the motors need more gas and in hot weather they need less gas.

Where are you at? If HOT AREA THEN LEAN IT OUT 1/4 turns CLOCKWISE. You should find a setting where if hot it will run okey and if temp drops 20 or so degress it will still be ok. But if the setting is to much for hot then when it gets really hot it will act up same if set to much for cool weather there is a medium setting that will allow the motor to run good in both situations. But you can always tune for best performance for hot weather and or cold weather, but then when the temp changes you will need to adjust the carb.

I'm from Cyprus. When the engine is hot its starts OK. But rpm is shaking up and down. It was 2000rpm steady. Now it drops to1.5 then goes to 2.2
And the weather didn't change to much its like from 40° to 30°
And don't know how adjust the carb without taking it of, because the bolt is on the bottom side.
