Welcome to the forum. Here's a copy of the service manual. Save it on the computer.

Print out a copy and put it into a 3 ring binder. You will be using it frequently. You can get plastic sleeves at your office supply store, and slip the pages you're going to be using for whatever work needs to be done, into them to keep the pages free of grease & stains.

Good pics in this one, and parts you will need for a carb rebuild. There are over a half-dozen other thread links here as-well.
The search function is your friend, use it to research issues you encounter, and what others have done while working them.
