Motocross turns off while driving?

Goodbye,

I have a Yamaha YZ250F, model year 2004

It hardly starts without pushing, and if it does, it usually stalls.

I only have one adjusting screw on the Cross for the fuel supply to the carburetor…but it doesn't seem to make any difference…

Anyway, if it's running and you keep your foot on the gas it stays on, but if you pull the clutch and stop accelerating, for example, it just goes off. I can't do anything to stop it from starting except not accelerating.
Kicking it off afterwards never really works either.

I don't really want to go to the garage and spend another €500-600, does anyone know what I have to do?

When was the last service?

When was the spark plug changed?

When was the last time the valve game was set?

When was the last time the cylinder was controversial and the piston was changed?

There is guaranteed not only a set screw on the carburetor and what kind of screw you've always twisted: it's guaranteed to change nothing on the "gasoline feed".

Read the basics of the carburetor agreement and get the workshop manual.

It does not necessarily have to be at the carburetor.

The KTM has the same gasifier, Keihin FCR 37.

If you want to cross with such an old grotto, you have to acquire the necessary knowledge and create your own hand.

Ideally, among other things, one is in a Motocross association and has comrades that help.
