Parts to keep on hand

I'm working on a kart for the family and getting ready to order parts. Which parts do you order duplicates of so that you are sure to have a replacement on hand? I was thinking chain and belt, is there anything else that breaks/wears out more often?

The belt for the torque converter is by far the most frequently replaced item. If the sprockets are both new and the chain also it should outlast MANY belts. Another thing that could ( will ) eventually let go of the throttle cable. As Fate can play a big role in what in what can go wrong or break it is almost impossible to plan for everything. AH HA . One more thing that I can think of that has failed for me is the pull starter. In an emergency I have rewound the cord well enough to save the day. If you are running a predator or clone engine
a new pull starter mechanism is about $14, and fits all the engines. It is 3 bolts and takes about 3 minutes to change. I always take a couple when we go to the
desert. No more winding up the old one for me. Too cheap and too easy to just
put a new one on.

People discard perfectly serviceable spark plugs like nobody's business. They can and will last a long time if you don't mind cleaning them, filing the electrode flat and re-gapping them.

They are an item that either works or doesn't work and will keep working until the side and center electrodes are too worn away to make a reliable spark. But people replace them once a year or less and it is often because they used the "parts-cannon troubleshooting method" (replace everything until it runs again) to get their neglected lawnmower running again.

Once in a while you will run into a spark plug that fails to work right out of the box or fails prematurely (have heard this about Champion plus more than any other) but that is not the norm.

Yeah I usually run them on a wire wheel to clean off carbon deposits, re-gap/check gap and re-install. Few hundred hours is usually their limit.
