I'm not, discrediting the information as bad, just not as applicable to o.p.e. as it would be to other engines is all. I get into fight quite often with guys and our rc engines running excessive ratios for no real reason other then hear say. 25 to 1 and 16 to 1 are "normal" ratios in rc 2 strokes (not nitro/glow engines) but nearly no one that doesn't race can tell you why they run that ratio, other then Jim Bob super moto gp racer runs that ratio in his husqkawsakimaha... so no reason in particular. But the same guy will complain that he has 3 gallons of gas through his rc engine and it's go so much carbon and spooge coming out the exhaust he doesn't know what to do. Usually it's from the excessive oil ratios being used in an engine that doesn't see the high sustained loads the moto gp/ mx riders engines sees, coupled with the guy can't tune an engine if his life depended on it.
It all needs taken into account when selecting what ratio/oil you run. Doesn't mean it's bad information, just needs taken in context with the application you're using it for. (I think that made sense.)
