I gotta believe some people just have bad luck follow them Or they self generate it in the name of 'personal drama'..
Believe what you want, but I can assure you that the pressure washer problem was the result of not getting all the fuel out of the carb when I ran it dry. The big washer only gets used a few times per year so storage conditions are important, and that's why I switched to ethanol-free gas for most uses. If I'm running it all day or for a few days straight, it gets pump gas to save money, then gets flushed with the good stuff.
