Remote operation of Throttle and Butterfly Valve

[mm391]

I am attempting to design a component to remotely control the throttle on a mini petrol powered ATV as a little project. Initially I have had the idea to adapt a standard cruise control unit to do the job but was wondering if anyone had any other suitable ideas? (Obviously this will not go out on the roads purely for uses on my private land) but ultimately I would like to remotely operate the brakes, throttle and steering.

Also what would be the best way of testing the forces needed to operate or turn the butterfly valve? Obviously it is connected to a spring so that it the butterfly valve always closes when your foot comes of the accelerator.

I have attached a picture of the throttle cable and where it is attached to the carburettor.

Thanks for the post! Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?

A conventional automotive throttle body motor would have plenty of power because that is what they are meant for. You would have to devise a way to control it remotely. That would probably be a conventional radio control device like those used on models.

Many newer cars don't even have a cable or linkage going to the throttle body anymore. It is essentially fly (or drive) by wire.You might get some ideas at the link below.
