Now when i put the accelerator to the floor, the secundaries wont open even a bit. I have a non standard (but old looking) and partly home made accelerator mechanism, which most probably is the problem. I related some time ago already a too high pedal force needed.
Does someone has a picture(s) of the complete accelerator mechanism, to see which part(s) im missing? I will see if Carl has the missing parts.

If it's anything like a vacuum secondary Holley the secondary won't open just by cranking on the throttle if the motor is not running AND under load.
