STARTING PROBLEMS

    I found out that one of the springs for closing the chokes is considerably weaker then the other one.

    Due to friction of one cable the weaker spring could not fully close the choke in a random way.

    Why are these choke springs weaker then the ones for the throttle?

    Hi Jan,

    The choke or enrichers is a small easy to move lever. It requires less spring tension and more spring may make it too hard to operate in the cabin depending on your setup. Usually if the choke is not returning it is from the cable setup. Maybe a thick cable in the protective sheath or too tight a bend in the cable or corrosion in the cable setup. Water damage in the enrichers can cause this once in a great while from corrosion. Cables need lubricating over time too especially in really humid or wet climates.
    I would take a closer look at you cables going to the choke.

    Roger,

    All cables are OK. The cable end after the bolt attachment to the choke lever did touch the throttle bowden cable set up preventing it from full travel. Remedial action: just cut the long cable end and installed a new spring. OK.

    I do not like control by cables: I like push/pull rods which may not be always convenient to install.
