OK guys back in the discussion, hopefully a little more manerly. In an eariler post I stated the the glow 4 stroke is designed to eliminate is spent oil out the breather and exhaust. I was told by a fellow club member that these engines have a form of port from the crankcase to the cylinder to pass oil out throught the exhaust. As I posted earlier my Magnum .52 expelled all its spent oil out the exhaust when the breather got kinked. My concern is that unless this aspect of the design is addressed the engine would soon run out of oil unless a large amount was carried. What do you think?
