I know. I was pointing out why it is done. What kind of dreadful state do you live in that won't let you swap engines after you get your emissions sticker?

We have random testing in Ohio. And required testing in a few areas where pollution is high. I have never seen one of the random testing sites being set up. Richard Sohn has a single rotor running with both a Pport and one side port. He also manufactures spacer gizmos that allow the stock metering pump to be fed from a bottle on the firewall. So you can run any top oil you want and a different crankcase oil. I use 40Wt Redline racing oil, and Redline 2 cycle top oil in a premix at 1.6 oz per gallon.
Nothing that rich is required for a non racing application. Lynn E. Hanover
