Questions & Answers

My mower won't keep running when the pull cord is pulled. Most of the time it won't even turn over. It's been thoroughly worked on. However, there's a small spring- the size of one on a ball point pen. It has a wire circle at each end. Is this part of the mower and where does it go?

I'm not sure exactly what happened. My wife called me and said that the tire exploded. The plastic hub had twisted up like a straw.
I set the lawn mower up on blocks. Installed the spring, set the shafts key over the spring, slid the gear over top. Put the washer in place, used needle nose pliers to lock in the snap ring, put the tire on and used a 1/2" socket to tighten up the tire. Very easy.

Grease all parts and reinstall in reverse of disassembly and you are ready to go. Easy repair just pay close attention to disassembly and you are good to go.

Self propel not working
When we investigated the reason for the self-propel not working, we found numerous parts missing and the gear off the shaft. Replaced parts and reassembled and thankfully it is working like a charm. Just followed the parts diagram. And take your time.
