I doubt that you will find what you are looking for online.

They are not difficult. I've done dozens of them. I'd suggest that you do
them one at a time so if you experience a problem you can check the other
one.

You might want to get a gallon container of Carb Cleaner at the local car
parts house with an immersion basket inside to hold the small parts. Soak
the parts for 24 hours if they are really gummed up. Then spray the parts
with an aerosol can of carb cleaner to remove the immersion solution and use
compressed air to dry the parts. Do not put anything in the cleaner that
is not all metal such as the gaskets, the neroprem tipped float needle, the
plastic float, the seals on the needle valve, etc. A welding tip cleaner is
handy to clean the jets. A special screw driver is available to remove
slotted internal jets.

Wear nitril gloves when handling the parts as they come out of the immersion
solution or your hand will smell for a week and people will really complain!

Hope I didn't saturate you with information!
