What happens inside a chainsaw?

Yes, crudely speaking, that's what Chainsaw Cylinder Piston Kits do: in scientific terms, it converts the chemical energy locked in gasoline into mechanical energy you can use to "do work," turning a tree into logs, sawdust, noise, and heat. Here's a very simplified explanation:

1. The fuel you put in a chainsaw's gas tank contains, in chemical form, all the energy you'll consume cutting down and chopping up logs. To keep it nice and light, a typical chainsaw tank holds just 0.5 liters (1.1 US liquid pints) of gas (a car's gas tank holds maybe 45–55 liters or 12–15 US liquid gallons, which is roughly 100 times more).

2. The fuel feeds through a carburetor to mix it with air.

3. The air-fuel mixture passes into a cylinder, which works much like the ones in a car engine but with only a simple push-pull (two-stroke) action instead of the more complex (four-stroke) cycle used in a car. Inside the cylinder, the air-fuel mix is ignited by a spark (sparking) plug, burns, releases its energy, and pushes a piston back and forth.
   Gears carry power from the clutch to the sprocket that holds the chain.

4. The chain spins around the edge of a long-steel plate called the guide bar, spitting out wood dust as it goes!

Advantages

The main advantage of using a chainsaw—speed—is fairly obvious. It would be hard to spend an entire day chopping your way through a forest with a handsaw, but you could certainly do that with a chainsaw.
