Pedal throttle modification

Hi guys, this weekend me and my father have been working on modifying the electric gas throttle. Remember that i've ordered a gas throttle which is meant to be used for electric scooters. So i needed to modify it to a pedal. I am not so good at welding and i've asked my father to help. He made a metal basis which holds the scooter throttle. Then we've bolted a metal piece that would be the pedal itself. Behind it there is a bolt that we use to adjust how far the pedal can go. This way we can adjust the maximum speed of the go-kart. What remains now is to paint the whole thing. Please check out the result below.
