The carburetor and fuel system that's in question is flawed,....IMO.
The other thing is that some owners do NOT understand where and why the system is flawed.
Be aware that whenever the gasoline that's inside the carburetor is allowed to remain in the carburetor, after shut-down, the gasoline dries out and residue, gummmy-varnish STUFF is left behind such that it messes up the ability of the carburetor to perform.
IF you solve the problem by installing a manual fuel valve, it's absolutely important to know why this is done, and to know the proper procedure of shutting down the generator. Know that the main purpose of the valve is to force the generator engine to suck ALL the gasoline out of the carburetor, as the new way to shut down the generator. Of course, to make all this work, you must start out with either a new carburetor, or one that has been taken apart and properly degummed.
