DaveW-
You made a vary good point regarding the bronze bushing engines and the oil requirements, that is a hangup I have with a Glow--> GGL engine I'm planning. Now I'm glad I didnt just jump on you prior post


For a Gas --> GGL, while the GGL is much cheaper than glow fuel, it still has to use hot 4stroke glowplugs, and that aint cheap vs the occasional sparkplug in gas mode
