: Did he also show you how to install new spark plug gaskets or re-anneal
: the old ones?

: Yep.

Which reminds me... should one try to do that on the spark-plug thermocouples
for measureing CHT? It's always bothered me that they *replace* the original copper
gaskets.

No. As long as you get the gasket/washer/thermocouple on the same way
it came off, it's fine.

Which, by the way, is also true of the regular copper washers/gaskets
under your spark plugs, per my A&P.
