In view of last years very poor survival rate with engine failures, it is reassuring to know that good airmanship can result in a safe engine
out emergency landing.  Nice work Charley.

The following has nothing to do with Charley's recent engine stoppage but it did bring a few thoughts to mind. Misconception #1.  The engine requires a
minimum of x quarts but will run with no damage
on x-4 quarts. I've found by experience that a constant
speed prop running with even 1 qt below the minimum recommended oil can cause loss of prop control (overspeed) on some eingines.

Misconception #2. When the engine suddenly begins
to run rough or quits, richen the mixture. Maybe or maybe not!  If the engine is running rough due to a clogged injector as is often the case with new installations, richening the mixture will cause the engine to quit.  This is due to too rich a
mixture to the remaining  cylinders.  Sometimes leaning is the better course of  action. The injector body meters fuel to the cylinders based on air demand by the cylinders. The flow divider
carefully meters an equal amount of fuel to each
cylinder.  A clogged injector forces the flow divider
to meter an equal but excessive amount of fuel to
the remaining cylinders sometimes causing a total
engine stoppage.  Jim  Frantz
