I use it as a fuel stabilizer in seasonally used machines, (snowmobile, lawn mowers, weed wacker, etc.) with excellent results. Add some sea foam to tank, top of with gas, run till treated gas gets through carb, shut down for the off season. They always start right up when needed. But, I never buy gas with ethanol for my small engines.

Found a post on another site pertaining to this topic. This motor apparently does not a have a large oil delivery to the rockers. It is supplied through a small hole in rear cam bearing and journal. So once per cam revolution, the holes line up and a small amount of oil passes through, eventually filling the galley to the rocker shaft. Sounds like a poor system, but the components under the valve cover, ( tops of push rods, tops of lifters, and caps on top of valve stems ), are cupped, so once they receive oil, they retain it. Also, there is a small plug in the block behind the starter that is common to the oil galley above rear cam journal. I started motor with this plug removed, and there was a small oil flow there. This told me that oil was getting through the cam and would eventually get to the rocker. I was able to determine that the passage from the pipe plug to the rear rocker pedestal was open with compressed air. So, I finished assembling the motor, warmed it up again, set the valves, and changed the break-in oil. All is well. Ran it two hours yesterday with the brushcutter on, ran like a champ.

Never mind, I discovered the main jet on bottom of carb was screwed in tight, not allowing any gas in.
