Just noticed our #3 running cool. CHT down 25f, EGT down 100f in the cruise at 23/23. IO-360, 350 hours from new, no other issues.
Pulled through 4 great compressions after the flight with no differences.
EGT probes are old on 1, 2 and 4 - planning on changing soon.
Ran comprehensive ignition check in the cruise, no difference so can't see it is a plug or lead issue.
Suggestions welcomed, may get the shufty scope down the plug hole next weekend.
