1970 2-bbl Carter rebuild tips / things to watch or check for a first timer.

Yep, I have not ever rebuilt a carburetor before.

Kit ordered & I am sure it comes with instructions, anything additional to look for or check while it is apart?

New fuel filter already installed.

(low mile fairly scarce 318 car I love, so anyone suggesting to dump the 2 for a 4 will be openly scoffed at - that is NOT gonna happen)
