Al,

 How many hours are on your sparkplugs and are you useing auto fuel or 100LL.........Something to

consider before a 2000 mile trip.........Could be possible indication before the dreaded "SAG"..........

 

I don’t recall (have to check the engine log), but I’d guess maybe 20 hrs; only 10 ga 100LL; all the rest unleaded mogas.  I took a leading and trailing out yesterday to look at them and they look fine.

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.
