these are the main components of an engine
the difference between four strokes and two strokes.
what gas should you use for your small engine?
why should you use ethanol free gas?
ethanol contains water which when it enters the cylinder if you dont go through the gas quickly it can make your piston rust, potentiolly damgaing or ruining your piston. if your a kid like me you could do that so you have an excuse to get a larger piston and cylinder, but generally i would not prefer that.
