RTK & Silversurfer,
Very interesting, It is not very pronounced but is noticable.
To overcome it I changed my landing technique. I use to come in at 3-4 clicks above idle and when I was ready to touch down, I would drop the throttle to idle. The plane would slow touch down and then I had to wait until the engine speed dropped to idle before the plane would stop. Now I drop to idle and just bump my throttle every few seconds until I am ready to touch down. I learned this from another guy with a 3W who flys at a field close by.

If I had to guess, I would say that the difference is 200-400 RPM. It is very repeatable and just causes you to go around if it doesn't drop soon enough. I will say that my engine is on the rich side up until saturday where I leaned it enough that after 6 flights, all soot and carbon is gone from the exhaust except around the outlet nipple.

I am going to attribute it to the fact that my engine/ignition is different from everyone else and it is a condition that only I have. It is interesting that I have had people at competitions ask me why I land on high idle. Instead of going through the long discussion I just say because I don't want the engine to shut off. They just smile and figure they will leave the idiot alone <lol>
