    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.

    Eddie, thanks for your last post.👍
    I purchased my cable also from Kitfox Aircraft.
    They have them listed on page 23 of their parts manual.

    I also have the Macfarlane vernier throttle on my 4 and find it perfect with the weaker springs.
    Anyone heard of the in cockpit throttle balancing gizmo? Sound a great idea

    I also have the McFarlane cables for throttle and enrichener. They are expensive but worth every penny.

    I also post this often in the cable threads, but this is the best method of "cutting" these cables to keep them from fraying.

    Thanks! I didn't realize that Kitfox sold these. I did look at the catalog but the only vernier throttle mentioned was for the 912is (Kitfox Part # 99004.000). I would much rather give my business to John ... and get one already pre-cut to the right length
