I find it nice to coast down long hills (closed throttle) , Downshift with high rpm and closed throttle (Eng braking) , Long runs at WOT , Walks on the beach, TV pizza and beer.

It solves the "problem" that neither premix, or the pump can address. Lubercateing during closed throttle. Or are you one of those, "2 strokes don't suffer from lubercation problems" fellows?
