For a while now I have been seeing high EGTs on climb out (1450F or hotter). The problem only occured when using high power settings: it was never seen while in cruise or descent. When I see the EGT start to climb into the 1400 range I've been throttling back.
Possible explanations for the problem included an induction leak, a bad probe, a bad instrument, or a bad primer (although this one didn't make any sense to me).
It turns out the answer was "none of the above." The probe, which is mounted about 1.5" too close to the exhaust port, had accumulated a coating of lead and carbon. When this coating was cleaned off, the EGT readings were in the normal range during all phases of flight.
The problem was diagnosed and resolved in less than an hour by "Bill" at Triad (Burlington, NC). Triad refused to invoice me, saying that it would be more trouble than it was worth. Good people there.
