I guess that after 20 seconds the float chamber has gone empty and for some reason is not filled properly.

Possible causes.

Tank venting clog (to check briefly without sample tank lid)

Gasoline cock defective or gasoline filter cloged (times take off the Sprit hose at the carburetor and see if enough fuel comes)

Gasifier dimmer needle valve cloged (clean or replaced)

Please clean air filter and carburetor and check the spark plug for wear and electrode spacing.

Then clean the carburetor.
