accelerator pump issues

well i have a chiltons manual made specificaly for the 75 year the thing is that it says to put it in the middle slot and the rod should measure 2.22 in...wtf would 2.22 measure out to in fractions lol. but it also dont make any sence because the rocker plate goes in the opposite direction that the pump rod needs to go to activate it. meaning that while looking at the engine from the front the rocker plate rotates ---> while in order to activate the pump it needs to pull the rod <---...its all very confusing really...and yea Lex its a pain in the butt. however it only hesitates at low speeds.
