Delray, thanks for the pic, thinking back to it now I think I saw that exact same pic on DIY go karts. Yeah it looks so easy to build, just a pedal adapted to the sqare peace on the flywheel hub thing and a return spring. I have a shit load of briggs shrouds so I can afford to make a mistake. Probly wouldn't hurnt to run your enigne a little rich so it starts right off, not? :shrug:
