RE: DL-50 engine
Ha, no not a dumb question. To tell you the truith, when I started up my newest DL that's in my Edge I had the throttle reversed so when it started it was WFO. Luckily, I was using one of the retention devices provided at our club so I didn't chop my fingers off. That's a rookie mistake for sure, but hey...
Let me go look at my plane and I'll let you know...
Open is back - toward the rudder and closed is foward - toward the spinner.
Party on.
