I had a lawn mower, years ago. Wouldn't run very well on cheap junk
oil. Put in some good stuff, runs a lot better. Air cooled engines run
hotter.

I had the same problem with a B&S 16HP. I was advised to change the
oil in the engine. I did and the speed stabilized. I don't know why it
worked but it worked.
