I tried this technique in my Bulldog (IO-360, CS prop). It
shuddered and shook so much I went back to the "normal"
method after 2 or 3 seconds!

Nowadays, in my own Warrior, I
push the throttle to full for takeoff and don't touch it again until
I'm ready to land; in-between, I set power by adjusting the mixture
only, as recommended by the POH for best economy.
