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

Yep and all of them want $11.99 to $13.99 a can plus never put it on sale. I'll take NAPA sale price of $6.99 or $7.99 all day long.

More than likely a fuel delivery problem. Tell us what year your generator is. If it is 8-10 years old the rubber fuel hose from the gas tank is probably hardened and cracked and sucking air. That will give you the condition you describe.


What part of this OP statement don't you understand ?

I pull the fuel line off the carb while trying to start and its being presented in a continuous flow.


What's hard to understand.....is why are you so picky?..:S

The poster is trying to help - maybe skipped some of the posts, as yours certainly deserves...:R

The fuel pump is electric, and will run in the prime (off) position of the "start/stop" button

I would disconnect the fuel line and crank the eng, does the fuel shoot out? If not disconnect the intake side of the line and suck on it then put your finger over it and see if it hold vacuum. I use a clear tube on the line to see the fuel. If your line is good and you get fuel out of the pump I would put the intake line into a gal of gas and a half can of Seafoam and run it for an hr under load after you flood the carb with Seafoam and let it sit per the instructions on the can.
I don't have prime on mine.


If you hold the 'off' button down the fuel pump will run to prime the genny.
Not on my 20 year old Kohler. I wish it did.

You can get it at Walmart and if not there I have found it at Amazon at the same price.
