    What is a chainsaw?

    The clue is in the name! A ChainSaw has two main parts: a saw blade built into a chain, wrapped around a long metal guide bar, and a small, one-cylinder gasoline (petrol) engine (sometimes an electric motor powered by a cord or battery pack). The chain is a bit like a bicycle chain, running around sprockets (gear wheels designed to turn a chain) only with about 30 or so sharp teeth (made from a hardened steel alloy) mounted around it at intervals. Inside the engine, as the piston moves in and out of the cylinder, it pushes a connecting rod that turns a crankshaft. The crankshaft turns gears that are connected (through a centrifugal clutch, explained below) to one of the sprockets on which the chain is mounted—and the chain spins around.

    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:

    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).

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