Hey Bear,
This carb is one of the easiest to rebuild. There are not a lot of moving parts, or things that can go in backwards.
A quality rebuild kit will have instructions, however they will assume some knowledge and a service manual will be handy.
Get a nice clean place to work, preferably where you can sit down. Did I mention clean?
It basically requires some properly sized screwdrivers, needle nosed pliers and maybe a small wrench or two and cleaning chemicals. Lay parts out neatly, study as you go to remember where things came from - take pics if need be.
The most difficult and probably important part is the float bowl fuel level setting ( almost as important as cleanliness ).
The best way to adjust it is with carb installed and engine in running condition, called a wet adjustment, so you can remove the air horn to adjust the float. Chitons has a pretty good write up if you have one. ( hint ).
Anyway, I hope either route you choose is successful.
Good Day and God Bless.
Jason.
