I'm puzzled by your terminology. "Richer" means more gas, doesn't it? A

I use 32:1 in everything. Don't observe fouled plugs or other problems.

you are exactly right, Dave. But i wasn't going to argue with the know
it alls in the group. If you use too much oil, you will actually make
the engine run hotter, because the oil is taking up space that would
normally be occupied by gasoline molecules, hence a LEANER mixture. The
Stihl man explained AND demonstrated (with electronic thermometers) this
to us in a seminar.
