All of the repairs were very straightforward except replacing the pull cord. Be careful to remember how all the parts go together as you take it apart (maybe take pictures along the way) and try to keep the recoil spring in the mechanism. Mine popped out and it took a good bit of time to get it coiled tight enough to get it back in. All the parts I ordered were a perfect fit!

I have a fairly old Lawn Boy mower. The primer bulb was ripped up, and the air filter cover and element were missing.

Screwdriver, Paint can opener to slip the primer bulb over the base.
Remove the primer bulb from the white primer body on top of the housing. Then install the new primer. Then place the new air filter in place and place the new filter cover on. I was surprised to find the right parts since the mower is 20+ years old.
