RE: NEW DLE 20cc Gasser! (Data & Links 1st Post)
I think you've got it tuned right. From the way I see it you're bucking up against that rotten timing curve and that's what causing it to fail to idle down properly. Betcha ya a dollar it'll transition from idle to full and back to idle just fine on the ground? But in the air it won't and you wind up overshooting the runway.....
I had the same problem way back until I understood what was going on.
As for the full throttle thing, don't worry about that. These little pesky engines are usually at full throttle at only 1/2 to 3/4 open on the throttle plate. That's normal.
I'm rather irritated at DLE for supplying an ignition that acts like this one does. I cured mine by replacing it with one off a 50cc (#1) and it runs fine now, but I shouldn't have had to do that.
Be nice if they supplied a muffler with the dang thing too while they're at it. That's another issue with me. Getting tired of the racket.
