I think we have to dispel the misconception that oil from the breather being recycled into the inlet causes loss of power.
It does not.YS engines do it.Oil ratio goes up and you adjust for it..

I have to disagree... Look at it this way.
Your cylinder can only take in so much volume on the intake stroke. If you were running some ridiculous amount of oil (say 95%), you wouldn't be able to get much methanol in the cylinder at all, would you?
Naturally, I don't think a glow engine could even RUN with 95% oil, but I think this helps to illustrate how more oil in the mixture will equal less power output, all things equal.
One more thing.. Adjusting the needle valves only change the
proportion of air to fuel/oil mixture. It does NOT change the volume of air and fuel mixture that can enter the cylinder on the intake stroke!
