I’m finding that at about 100F LOP I sense that the engine is starting to not like it – like it doesn’t seem to be entirely smooth; maybe an occasional miss here and there.  Am I right that some of you guys run as much as 200 LOP; or is it my imagination – in both cases.

Would timing setting have much of anything to do with running LOP?

Just past by the 100 hr mark on the engine near the end of a 500 mile trip on Monday.  I plan to leave next Monday on a round trip of over 2000 nm over the following week.  That’ll rack up a few hours.
