I have a Champion and haven't experienced any issues with it. Since it's only called into duty during a power outage I keep the fuel reservoir full and doped with StarTron ethanol fuel treatment. Same goes for all my power equipment. Since most new equipment is emissions compliant, it doesn't take much to make a carburetor run a foul. Usually running a tiny drill bit one size larger(a couple of thou) than the original size through the main jet will correct poor operating issues.
