RE: Nitro eng doesn't need timing devices,why?
Needle bearings on the rod ends. We don't have them on glow engines and they do on the Gas engines.
I remember when the standard mix for 2 cycle engines, IE outboard motors, was around 10 to 15 to 1 gas to oil. Then they redesigned the engines to the point that they would live on 40 to 1. Needle bearings and better oil allowed this. Oil won't do it on it's own
