  • Re: Bowden cable fixation to throttle lever on carb

    by » 2 weeks ago


    I much prefer setting my "hard" idle stop at the throttle control.

     

    No chance of bending idle stops.

    No chance of damaging cable.

    Adjusts both carbs at the one point - no chance of out of balance idle stops.

    Readily adjusted, at one point, for winter/summer idle speeds.

     

    What's not to like? 😈

    This is the best way, but some don't have that option with a vernier throttle and they can pull back too hard and far and bend the idle stop plate.

    Hi Roger,

    "....some don't have that option with a vernier throttle and they can pull back too hard and far and bend the idle stop plate."

    Thats too bad.

    Speculation:

    Once the carburettors have been synchronised/set up, the adjustment to prevent the possibility of over enthusiastic closing/idle/damage to stop, is very small.

    Most throttle cables have a threaded fitting at the panel end .

    It may be possible to make small changes, to the movement of the throttle, by using a thin nut to move the assembly in/out (fine adjustment), lock in position with the back nut.

    Hi Sean,

    I use cable locks at the carb many times on certain aircraft because they don't have a stop in the cockpit. Vans RV12's uses them. Usually these are on Vernier throttle systems where you push and pull and pulling a little too hard can bend the idle stop plate and if you bend it a bit too much and shut the engine down..

    Hi Roger.

    I absolutely agree with having a hard stop before the carb idle stops  - just speculating on the simplest/most convenient way to achieve an equal stop.

    The above pictured is an example of a Vernier throttle, has a long threaded panel mount, that could easily be used to make small adjustments to the amount of available movement in the system.

    I have a quadrant style throttle - for  non contact with idle stops, winter/summer idle speed adjustment, I adjust the cable at the quadrant😈
