    Solex and Zenith throttle controls

    There was some discussion re the fitting of the the two different types of carburettors to a 2.25 engine and how to overcome the opposing operative strokes of the rod from the bell crank to the carburettor.
    This can quite easily be achieved by reversing the position of the bell crank assembly on the spindle so that the controlling link from the firewall to the bell crank operates on the opposite quadrant, that is from the top rather than the bottom, or vice versa depending on which carbie one is replacing.
    In the first picture (Solex) the rod from the firewall goes to the bottom of the bell crank which means the throttle rod operates in an upward direction.


    Whereas in the second shot of a Zenith you will note that the rod goes from the firewall to the top of the inverted bell crank operating the throttle rod in a downward direction.

    You may have to tweak (bend) some parts to get a more satisfactory angle but it is really quite a simple operation.
    Have fun.
    Regards

    ZD,

    thanks for the pics, but it does appear that both of your example have a different arm than the vehicle in question. The bell crack looks the same, but the arm the crank pushes on (which ultimately moves the link to the carby arm) has a single right angle return on it. Both of the samples we were playing with have 2 returns, one either side of the bell crank arm.

    Inc. pic of my 66 version attached with throttle held open. clearly shows different arm to yours.

    You had me all worried. My '59 CR has a stromberg on it currently, and I have picked up a Solex for it to refit.

    The Colonel checked it yesterday for me and luckily the correct linkage is still there.

    Phew.

    fitted after quite a few hours of being mucked around by various length lvers and the like.

    i have now found 3 different length levers for the carby side of the firewall rod!

    anyway, it is fitted!

    i need to rebush sometime in the not too distant future

    many thanks to all concerned!
