Agree. I was answering in terms of the mix ratio. And on that subject, let's ignore the break-in factor - If I may read between the lines of the "yes or no" required response.... deacon could be asking: If I don't change my jetting at all and make my pre-mix more oil lean ("1/35 instead of 1/20") will I make more power? Here's some thoughts:
1) By leaning back your oil, you will actually make your air/fuel mixture more fuel rich. Will a more fuel rich mix make more power? Only if your air/fuel mix was too lean before.
2) By leaning back your oil, you may compromise piston ring seal a bit. I have to think these crude 2 -stroke engines need all the ring seal they can get (I could be wrong), but even I, "King of Oil Lean" will not go beyond 40:1. We'll see. Some loose race only engines make most power at less than 20:1.
What about MPG? Again - in a perfect world, if you change the oil mix ratio leaner and nothing else changes, your MPG may even go down a hair.
I'm not sure if you saw this:
