Intermittently, my engine
will climb a couple of hundred revs from cruise
power for 10-15 seconds, then return. Usually not until the engine
is warm, and very intermittently. On a recent cruise
, didn't do it at all one day, once an hour or so the next.
Any clues on what to look for? One crew suggested a fuel
system air leak, but I would think it'd hesitate instead of over revving......
