    Buggy throttle pedal very hard

    Hi
    I have just bought a old autograss buggy and i am currently on making a new pedal box for it.

    Finished making the throttle pedal today, connected it up and its really hard to push. It feels as if inner cable is grinding in the outer cable.
    It has got a few bends in it but nothing i would class as tight.

    Anyone got any suggestions to what i doing wrong??

    Should i lube the cable?

    Any help would be much appreciated

    Thanks

    Without seeing what you've installed / working with its tricky but ANY bend adds friction - ideally no bends at all or one big radius loop for ease. I'm guessing its a relatively long cable as well? - doesn't help! Most cables are lined with ptfe/nylon so 'wet' lubrication just causes stiction.

    The cable is 3 meters long and has a large bend at both ends.

    Just had a look in the outer cable and it doesnt have a nylon liner its just the coiled metal so i dont think thats helping.

    Might buy a outer cable with a nylon liner and try that

    It could be any manner of things, too stronger pull off spring, frayed or rusty inner cable or the wrong pedal ratio. You need to disconnect both ends and see if the cable moves freely and work from there.

    The cable is brand new only 2 days old. Inner cable is clean no rust.

    The throttle on the carbs turn easy by hand

    If you disconnect the cable both ends it pulls really easy no resistance at all

    Connect it back onto the carbs and you can hardly pull it.

    Connect both ends up and the pedal is really hard, far too hard to use properly.

    I think with the outer cable not having a nylon liner in it it is metal on metal on the bends and causing too much friction
