so, since John mentions the vernier assist being a different story. For over two years now I have had my throttle require "firm" deliberate force to actuate. On my trip to OSH I loosened up the friction lock and found the throttle to be much more enjoyable to use except one finding I noted. My throttle creeps open, assuming due to the spring on the throttle linkage at the engine. If I leave the friction lock engaged the fine adjust (twist of the knob) works great. Bottom line, I have to leave the tension in the friction lock so the throttle doesn't creep which adds some resistance to actuating the throttle. Not sure I want to remove the spring but I would enjoy the reduced force needed as when the friction is removed.
