the throttle friction is a weak link, the nylon washers tend to turn
unpredicably so there is a tiny bit of lost motion at closed position.
Better to use nylon plates anchored to the box to get rid of the lost
motion.
Imho 2000rpm is too much, with carbs balanced you should achieve a nice
1750 rpm. You're right about the stop/lost motion. The whole box is too
floppy imho.

You should find that if you trim out clean at 80kts, lower the flaps and
you have 60/65kts trimmed. That's ideal, no retrim needed while you are
busy.

I recommend small amount of power on finals but trimmed at 65kts. Easier
descent rate.

Feel for the ground with tail wheel, then stick hard back. There will be
a small bounce but no balloon because aircraft can't pitch up any more
with tail on ground. All you need to think about then is keep it
straight and that means instant response to yaw, especially on black
top. Grass is more forgiving.
In ground effect the tail loses the downwash from the flaps/wings. The
nose drops, wheel touches and she balloons, (unless the tail wheel is
already on the ground ) ;-)
