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........Even though I have heard of leaning up to 200 LOP = I do

believe 100 to 150 LOP is a more practical range.........
