Answer 1

engines are built around using the inertia of the cylinders and crankshaft spinning to move them form power stroke to power stroke, and siphoning off the rest of the energy to do work. If you put too much load at once on the engine, you draw too much energy “out” of the system and then cylinders fail to properly compress the fuel to power the next cycle, dont ignite properly, and then theirs no more power for the next cycle.

​

modern engines use an electric starter to get them going, which is basically a small electric motor to spin the crankshaft and cylinders. other engines might use the ripcord for the same purpose, or even the old school hand crank.
