i need a pdf or jpg of spring assembly for 4.5 b&s?

i would like to know if i can get a photo or pdf drawing of the spring assembly and the "piano wire" pushrod that regulates the starting and throttle of a B&S 4.5 lawnmower engine---thank you!

this is an "on only engine" there is no actual manual throttle control the only feature is a lever you pull up on handle bars that allows engine to crank)
