Yea I've looked at these but there's not enough detail.Welcome to MLMF Cohiba54.
It's been awhile since I looked through the Lawn Boy manual, but maybe your answer is in here somewhere. If not, I'm sure somebody more familiar with Lawn Boys will be a long to answer your question.
This exploded diagram might help a bit too. The primer is parts #20, 21 and 22.

Thanks Brad. It's one of those things that if you didn't take it apart or something was missing to start with, just just has no idea which end is up.On your carburetor there should be 2 hose connections, 1 larger than the other. The smaller one is where your primer hose hooks up. The other end of the primer hooks up to the primer fitting. It's that simple. When you push the primer, it forces air into the carb bowl which pushes fuel up into the carb throat. Should not have any problem hooking it up.
