previous posts regarding how much oil to mix per gallon of fuel.
Unfortunately, that message is floating around in my computer
somewhere....doing a very good job of hiding.  Looking for oil to fuel
ratio. I assume I can just use my 2 cycle oil that is designed for
air-cooled engines? (Same oil as I used in my Rotax powered gyrocopter).
Thanks in advance to all who respond.  Paul Conner
