Loose EGT probes

Have you dynamically balanced the propeller? I balance props on all size engines from Rotax on up. I have only once had a prop that was within balance limits. What I am saying is if it hasn’t been balanced it needs it regardless if it “feels” smooth. 

Thanks for suggestion.  I have not yet done that because with so few hours I may still choose to make a prop pitch change.

I had similar issues with my 914 probes becoming loose without any antisieze used. Carry some wrenches and tighten every few hours until the compression fitting seats.
