sticky throttle

I've tried several different spring combinations as well as different tensions but the throttle on this ez-efi still hangs open if I use anything but a spring that is so stiff that you cannot control the pedal. in other words you have to really jamb your foot down to over come the tension.
It seems to me more of a mechanical angle problem, spring verses the mounting points around the throttle shaft, verses the mounting point on the motor. Anyone using two springs? or pictures of their set up? It's not the throttle cable; I checked that.

By the way I'm working on a 72 Buick 350 motor.

This is what I have and I have no problems with it closing.

thanks David!
After much trial and error I ended up raising the stock throttle cable mount an inch and a 1/4. that reduced the pedal pressure a whole bunch. Actually the angle of the cable and springs are not much different than your set up, parallel with the throttle blades. I was bird doging down the wrong path for a day or so. We are up and running now.
