REFLECTOR: EGT Temps

[John Dibble]

Ronnie,
I'm also trying to figure out what is a normal egt for the Franklin
engine.  Maybe 600-650 C (1112-1202 F) is ok and I shoudn't worry about
it.  My other egts run 400-450 C (752-842 F).  Maybe these are low
because the sensor isn't getting the true temp on the outside of the
exhaust pipe.
