I purchased the above engine this winter in Texas. It may have sat for over a year. It had a half tank of fuel so I filled it up (30 gals total). The engine ran good until it got down to half a tank then it idled rough and at full throttle ran at about half speed. I changed the fuel filter and put in 8oz of ethenol stabalizer. It ran good for a half hour trip. We sat for about an hour and when we headed back it again idled rough and at full throttle ran at about half speed.
