What's the difference between a Motor and an Engine? I'll tell you. A motor is powered via Electricity. A Engine is powered via Internal Combustion. Long ago when dinosaurs roamed the earth I worked at a car dealership as a lot person, after school job when I was 16. I was in the mechanics bays and overheard a mechanic call an engine a motor,,, I pointed out the difference and was told,,, you are right, my mistake. From there on when there wasn;t much to do the mechanic took me under his wing and taught me some stuff.. Came in handy too later in life... Ever rebuild a carburetor on the roads side? I have. Many years ago I knew I had to do it,,, didn't plan on road side,,, but good thing I bought the kit. How'd I get the nick name Smitty? now you know.
