Make a lever like this, see this one 'gears down' the throttle rod to the carb. The pedal actually travels more than the rod. Just put your carb cable outside the pedal cable, from the pivot. I used the factory governor arm for this one, I drilled a set of holes in it so I could pick the right ratio to make it come out right. There is a return spring on them on other side.
The choke on the right I used the other side to change direction of it. There is more pics on page before that but not good ones of linkage.

You don't really want the carb to go all the way open anyway do ya? LOL! Let us know how the carb works I want to put one on my clone I think this carb sucks. I'm trying to make a curved intake.
