I take so much stuff it would probably be embarrassing to list it all. Instead, I'll give an example.
This is my gas auger emergency kit:

It is built into a cute little Tupperware container, with everything organized in polyethylene foam, cut to fit. On the top level we find
-Mini ratchet
-Spark plug socket
-Auger blade screws
-8mm wrench for blades
-Silver washers (part of auger attachment)
-Brass-looking spacer thing (part of auger attachment)
-Spring clip (also part of auger attachment)

Then on the back side we find
-Stubby screwdriver
-Spark plug
-Spark plug gapper
-Collar bolt
-Hex keys

And tucked into one side a spare auger blade:

Just another thing I take and hope to never use, like my ice spikes or my spare clothes in the truck.
