Default Do 4stroke engines need to use 4stroke fuel?
I just bought an OS 56 alpha. Was using Cool Power 15% heli mix to break-in the engine. Noticed at full throttle, the temp at glow plug hit 276F. Is that too high? I tuned it to max power, then richen a bit. Should I be using 4stroke fuel instead? I also noticed at idle, there are alot of vibrations. Am I using the wrong fuel? Thanks for your replies.
