Just putting this out there out of curiosity to see how everyone learned the way a four-stroke engine works. Back when I was taught by an old man I learned a way to remember it that I will never forget. As we all know it is intake, compression, combustion/power, and exhaust. Now the way I was taught is suck, squeeze, bang, and blow Now if that isn't easy to remember I don't know what is ha ha. Anyone else learn it this way?
