after i built my injection pump, i couldnt get it to do anything besides idle either. i bet the throttle arm is off a tooth or 2. and i bet the fuel screw needs to be messed with. i moved my throttle arm 1 tooth, screwed the fuel screw most of the way in, then voila, it lives. and im glad it works. biggest improvement ive made to my engine yet. its definitely gonna eat some hondas now.
