I just paid for a new carburetor on my lawnmower.
The old one was eaten up by ethanol fuel.
The aluminum just started turning to powder, the mechanic called it “white rust”.It is the result of water in the ethanol causing an electrolysis like event.
The crap gets down in the Needle and seat and plugs it up. The machine runs until the bowl empoties , then stops and starts a while later after the bowl refills.
New carburetors aint cheap.
Try Star Tron Enyzme fuel stabilizer. It seems to work the best. I have tried them all. I would suggest only buying gasoline one gallon at a time. Also, buy super unleaded instead of regular. Lastly, if you have a machine that does not get used every week(like a brush trimmer)empty the fuel out. Never leave fuel in the tank in the off season. You will definetly plug you jets. Ethanol will also dissolve the rubber fuel lines.
