/diy/ - Do It Yourself

I'm interested in learning mechanics and shit and working on cars. I've heard working on lawnmower engines is a good place to start. But I really don't know what I'm doing.
What am I supposed to do, take an old lawnmower off the side of the road and fiddle around with it until I've pulled it apart? Then what?
I'm guessing I'd want to try and fix broken ones. Anyway as I say I've got no idea what I'm doing and no idea where to start. Is there some guide out there that can hold my hand and tell me what to do?
