armody (and others),
I don't post on here too much anymore, but still surf once in awhile. If you do a search on here you will find all kinds of info on the DLE 20 with the #4 ignition, and the timing advance. But, if you go to pge 180 of this thread and look at post 4480, you will see my post way back when regarding the timing. The link to the YouTube video that my son made is still there. On the video you will see that I am making very small throttle adjustments with the trim tab of my radio.
Lots of people will say that you can fix that timing issue with proper linkage set-up and proper tuning of the engine. We'll, you'll see that I just changed my ignition. That to me is the easiest way to fix the problem, becasue my Extra was a SOB to land with the stock ignition.
The DLE 20 was my third gasser, and I can say if it had been my first, I probably would never buy another gasser. It was very frustrating at first. That's why Jody sent me the ignition.
Once you see the video, you'll understand why.
One other thing, the ''experienced'' engines guys at my club helped me a lot with my first two gassers. So when I had them take a look at my DLE, they all just shook their heads. At the time, none of us at the club knew about the automatic timimg advance. It's a real thrill landing an Extra at 3400 rpm, and then watch it drop to 1800 all by itself at 10 feet above the ground and just about nose in.
It is soooooo much fun to fly now.
