Seafoam Treatment
I can't keep my Onan KY4000....H generator running unless I spray a continual mist of seafoam treatment into the air cleaner. Would this mean carb issue or control board issue? Thanks Len

It's definitely a fuel related issue. I'm not familiar with the Onan so bear with me here.
Remove the carb drain plug, or open the fuel drain screw. This will be on the bottom of the float bowl. A drain screw would be near a port or hose leaving the bottom of the float bowl. With the drain removed, you should have fuel pouring out since you've already established a good fuel supply to the carb.
If fuel is not coming out of the drain, you have a stuck float valve. You may be able to reach in through the drain hole and tap the float, but be careful to not press hard or the float level could be altered. Or remove the float bowl completely (probably require carb removal) and try to exercise the float to dislodge the float valve.
