Out of the mouths of babes: Noob, you'll be happy to know that you were right on. I just got home from burning my second tankfull of my old original mix using a 25:1 Stihl, 2 cycle oil. The Chris Hill motor has regained its performance almost completely. On the test hill in my neighborhood I just climbed it at a steady 21mph which is about where it used to be.
Okay guys, I'm open for suggestions. There are too many satisfied Opti-2 users for me to believe that the oil is bad for a motor so what the heck happened to my engine? It is running strong again and everything is back to where I started; original carb and ignition, everything. I plan on calling the oil manufacturer tomorrow to see if they can shed some light on this phenomenon. I'll let you know what they say.
