Loose EGT probes
I have a new 914 on a new zenith 750 STOL. All four egt probes consistently come loose after just 20 minute flights. Both the egt probe and the little adapter come loose. The exhaust had factory holes already there. The probes were first installed with anti-seize. The carbs have been synced and things seem to run smooth. About 5.5 hours on the engine now. Any help would be greatly appreciated.
