Ok, I have a manual and followed the insructions on adjusting the fuel saver rod set screw. I followed the instructions in this picture i posted here. But now, when I advance the throttle all the way and the spark advance is at the maximum (ie: the armature plate bracket (D) is resting against the boss (F) on the block), the carb butterfly is somewhere between vertcal and horizontal. Under no scenario does the butterfly now get to be horizontal. It should be horizontal at wot, correct? Or maybe a bit less than horizontal because of the adjustment i made employing the fuel saver option.

See #3 in the instructions. With the armature plate against the stop loosen the collar and let the rod go where it wants to go. Then slide the collar into proper position, just touching the pivot pin, and tighten the screw. Now, as you advance the throttle control most of the movement will be moving the armature plate until it hits the stop. Then, and only then, should the pivot pin contact the collar. Further movement of the throttle control kicks the lever over center and opens the carb butterfly to horizontal.

Frank: I’m with you to this point (the part in red) I think. But how do I advance the throttle at this point? My throttle lever is already in the fastest position and the armature plate bracket is already up against the boss on the crank case.

And then the part I made green: where does this "further movement" come from?
