What's your technique Scott?
Well it's a very detailed, scientifically validated protocol, and I'll
attempt to outline the specifics he
For ground operation, I'll pull the mixture out, oh, about an inch and a
half or so, give or take.
Full rich for takeoff and climb, up to about 5000 ft or so (home base is
at sea level). Lean it a little for climbs above 5000 ft.
For cruise, pull the mixture out, oh, about an inch and a half or so,
give or take depending on altitude (pull out more at higher alt).
I have no engine monitor, so I used to pull the mix untill power loss,
then enrich slightly for cruise, but it always ended up in the same
place, so see above.
Thats it, as far as leaning goes. I cruise at 23 square, get about 150
mph on 12 gph.
I try to keep manifold pressure as high as possible. After takeoff, I
leave the throttle full, and pull back RPM to 2450. For power reduction
approaching the traffic pattern, I pull the RPM's down with the MP, down
to 2000 RPM and about 18" for pattern entry. My theory is, higher
combustion chamber pressures should help scavenge the lead better. This
theory is based on nothing but my gut.
Happy Flying!
