To hell with manifold pressure. Try coming back on the throttle until you
have 1900 RPM and 80 knots in the downwind pattern. When you are abeam your
touchdown point, apply 10° of flap and reduce to 1800 RPM and hold 80 knots.
Turning base, crank in 20° of flap, reduce to 1700 RPM and 75 knots. On
final, reduce to 1600 RPM, 30° of flap and 75 knots. Further reduce RPM as
necessary to hit your touchdown point.

On e helpful addition (for noise control): This works on all
controllable-pitch airplanes, too.

Do NOT push the prop control to fine pitch until you are throttled back
and slowed down to approach speed! This way, the governor will set the
prop pitch at the stops and will probably not exceed 2000 RPM.

Fly the approach speed, flaps as necessary, throttle to control glide
angle. If the runway numbers appear to be going away, add throttle; if
they appear to approach you, reduce throttle and/or add flap.
