RE: DL-50 engine
Weez, Yep. Looks a smit lean and the reason I say that is if you get into a Situation were you go any leaner, you may sustain damage. super8 and the bunch could tell you better but for me I like a little safety margin on that. Some engines for other uses I have had, I would call that a clean burn but not in an aircraft. Mabey a few more will comment. Blue Skies.
