Yes, compression is good. Plugs show no sign of running lean -- every plug is a nice tan colour. They don't look hot to me, no overheating or blistering is evident. The plugs that are part white are also part Tan! Look at the photos carefully to see what I mean.

Apparently this half/half plug condition is not uncommon. Searching, I see it is reported from Nissan to Chevrolet and from chain saws to snowmobiles. No one seems to know what is is, but people are guessing at the cause -- all different sorts of guesses.
