Briggs Stratton Intek 22hp, choke issue

I have a B S model 44n6770045g1mm0024. Starting when cold requires manually lifting up on the linkage rod going to the choke. This unit has a throttle lever that when pushed beyond full speed operates the choke. When pushing the throttle to the choke position it has no effect on closing the choke. The rod that pushes the choke pivot is connected to a horizontal lever that pivots, but opposing end is not attached to anything. I cannot figure how this choke is to function.

Hi Scott, I have a been looking at those same diagrams. In diagram 222, there is a bracket sticking up at 10 O'clock. That hole at the end is where rod 216 hooks into. That bracket, sticking up at 10 o'clock in 222, has a pivot point, but on the opposite end, as the hole, (cannot see it in the diagram) there is nothing controlling it.  That bracket needs to pivot up to engage chock. Thats what I do not understand how that choke is engaged.
