anyone run a push pull throttle cable set up? it seams that the carb is set up for 2 cables I think this would solve the stiff spring problem,my xr650 has two cables and a 2 year old could twist that throttle. I just put the pumper back on my ds and man thats a hard twist, and when i try a softer spring it sticks what cables would work on this carb? just a thought
