I remember the O.S. part worked very well. Never really seemed "complex" as the linkage was just like the throttle. Maybe the rock bands of the '60's, un-muffled model airplane motors, and high speed dental drills took a toll on my hearing, as I never seemed to have the best "ear" for setting the needle. At any rate, it always seemed like a nice convenience and even a safety factor, as you could tweak it without having to reach anywhere near the prop. Thanks again for everyone's help.
