Thanks Ralph, Kris, and Diablo,
I will say it looks like my engines are run rich. My next question is: I have been told that you always run with a tan plug color. Not black. I have never had a tan plug on my BME. I have had a tan plug on my Brison engines. I adjusted the carb the same way with both engines but with different results. maybe I just got lucky with my Brisons. I guess I will keep leaning the engine until it shows poor transistion or sagging on uplines. For me it is hard to tell if an upline is sagging. Usually the plane does not look like it is slowing down until it is too high to see the pilot in the cockpit. I always contributed this to perception instead of reality.
