It's fairly simple.
You need to rotated the linkage 180
Enlarge the linkage throttle cable hole
Block off the bypass port
Cut off the throttle stop tab (for closed throttle)
Make a throttle stop (I just used heatshrink on the linkage)
Optimize the crap out of it.
Shim the gas pedal cable (~1/3") to take the slack out.
I'm sure I'm missing something...
