Yes, Daryl - I also never pushed props to high for landing. I figured it would be fast to do in an actual go-around. Perhaps once or twice did I do it when I went into really tight airfields, like Johnson Creek or Bacon Strip. In general, tended to not touch props at all after T/O and the first RPM reduction.
Never heard that about pressur carbs, but never had any problems with mine.
Man, do I miss flying the 520! It's just a little joy of get-up-and-go'ness that thing. When you get a bit more comfortable in it, try doing the Full power, 2/3 flaps short field takeoff and you'll see how insane that thing is - she'll start climbing out at 45kts!
