Al,
I notice that is a non-resistor plug. Do you get any radio
interference?

lean of peak
What plugs
are you using currently Al ??..............Might be worth a new set
of plugs and a test flight before your trip to see if
you get the same symptoms when
leaning.
I’m using NGK B9EGV.
It’s easy enough to put in a new set, although I normally order them
on-line since they are pretty spendy at the local store – if they have
them. I don’t think the plugs are the issue; I think Dave’s
point about some unevenness in the mixture between rotors is the likely
culprit. It will be easy to see when I get flying – which may not
be until I leave on the trip. I’m not too concerned since I can get
over 20 mpg at 200 mph with EGTs below 1700F.
