Have a clean workspace I like the pan idea, but I mean bigger than that. Have all the tools you think you will need close at hand.

Cover that with white or brown paper and tape/tack/pin it down so it doesn't roll up on you. NO newspaper . . . you can't see small parts on bad news about the economy!

Put screen wire in the basket that comes in the gallon of carb cleaner so the tiniest parts won't slip through. Get a spray can of carb cleaner too! Its really good for small passages.

I like the old style paper egg cartons for putting parts into.
DO NOT USE the plastic kind . . . even a drop of gas will eat them immediately. Label the parts you remove in some sensible way
you understand.

Go step-by-step and take your time. Try to remember the sequences things are done. Don't get rattled if you get stuck. Reread and rewatch your videos and paperwork. Plus you can ask here!

There is a first time for everyone. I know you can do it!

best wishes,
