One time, when I was 10, I tried to fix an old lawnmower engine. I
wanted to attach it to the chassis of a homemade steel tube go-cart, and
race around the neighborhood.
I could not fix that lawnmower engine.
However, I can fix a rewind starter pull cord. I've repaired a few of these, and the last time I attempted it, I took photos.
Lawnmower pull cords break all the time. The cord gets wet, it sits in the sun, and it is subjected to a rough series of yanks every weekend in the summer. The cords are under a lot of stress.
Some lawnmower cords end up as alcoholics. Others snap.
Lawnmower cord breaks provide a short, fun repair project that will temporarily interrupt your lawn mowing duties.
First, some background: A lawnmower pull cord is a lot like the string on a spinning toy top. At rest, the cord is coiled up around the outside of a round
wheel called a pulley. As the cord is pulled, the pulley spins in place. This spinning pulley is attached to the main motor shaft, which, once it is warm and operating, makes the whole machine fire into life.
These are the steps to replace the cord:
I found 1/8th inch cotton cord at Home Depot. The bright yellow cord was the cheapest, so that is what I got. Steel guitar strings would never break, but they would probably rust.
I think all of the bolts were 10mm.
