I'm flying a club owned C-172 C with the Continental 0-300 engine. The club & plane owner has given me some very specific instructions about managing the engine. Never idle below 1000 RPM. Run full rich below 6000 feet. Don't run it in the 2000 RPM range (there is a bit of vibration there).
I find I'm having to adjust some of my pattern habits to meet these instructions.
When I trained (in a C-172N with the Lycoming 0-320) if my downwind was extended, I'd throttle back to 2000 RPM and just slow fly until they cleared me to turn base. There's no need to hurry away from the airport just to fly back again, right? But that engine setting is right in the vibration zone prohibited by the owner.
Likewise, I find idling at 1000 RPM makes for an uncomfortably fast taxi speed. Or I have to ride the brakes. Also, it adds a noticeable bit of thrust on final. I'm used to pulling the engine all the way back to idle on short final.
The full rich below 6000 feet is not how I was trained, but I haven't flown that way enough to see what it's doing to fuel consumption. I rent dry so I do care.
Are these kinds of things normal for the 0-300? My impression is that this is a very well maintained airplane and it performs reasonably well.
