Here are a few pics of how i converted the original pedal to pull down on a cable. Sorry one pic is blurry but you get the idea. Its basically a slot cut in the end of the pedal rod where i chopped it. I welded a washer into it and then its just a simple clevis pin hookup. Its super tight to get your hands in there to hook it up but it does work well. That pic looks like a weird angle but after this i did some filing on the clevis and its straight now. Also that’s actually full throttle. I rarely need to use more than 20% throttle at any time. Normal cruise at 55 is probably like 5%.
