Ben, Yeah. Actually, this has not yet happened in the Piper Turbo
Arrow III that I just bought. It happened pretty frequently in the
Skyhawk Millenium that I used to rent. I am asking because the TCM
booklet seems to be pretty hard-over on NOT doing burn-out procedure.

Well, I was taught this time-honored way. What the book does not say is
what you are supposed to do when you get roughness in one magento. Ideas?


If you lean aggressively during taxi and avoid full-rich descents you
probably won't have any fouled plugs to worry about (we are talking about
OWNED aircraft, right?). And then engine roughness on the mag check is
probably NOT plugs, so why abuse the engine to try and fix it?
