I no longer buy OS two strokes for myself but I also don't use anything smaller then a .91 two stroke glow engine. If I need a small two stroke I have boxes of them under my bench. I started using the SK line of engines in the glows and they suite my uses better then the OS line of two strokes. At a hundred bucks a pop they even fit my wallet. I use almost nothing but four stroke glows and if I have to buy one it is a YS but I also like the OS and Saitos. I don't buy OS or Saito though. If someone says here you go, you can have this but it can stand some work then it's on my bench getting a rebuild right away. It was a big surprise how many people don't rebuild engines and just toss them or give them away. Works for me though!!! After 1.20 glow I head right to gas and save myself more money in engine cost and the price of glow fuel.
I feel OS still makes the best of the small two stroke glow engines and to date I have never had a problem with one, with or without bearings!
