Robert, Hang in there and get your hands dirty. You can read all day about fixing something but never know anything until you tear into something. What have you lost if you mess up? Your Dad can put it back if you can't. It's not like your trashing a $2000.00 engine. I started with a service manual and some rusty tools in a converted chicken coop that I cleaned up and put a table in. I remember the first engine I worked on. It was a old Cast iron engine from about the 40's. Rusted up tight. I spent hours soaking the engine in Diesel fuel and wacking the piston to loosen it up. I learned a lot from that tear down. No, I never got it running but it was my start. I was 13 at the time. Your way ahead of me in knowlege. I would say buy a manual and keep asking questions here.
