"It's never the carburetor." Tell yourself that now with conviction.
Save the carburetor for last.
Do a simple test of how much fuel the fuel pump delivers into a Diet Coke bottle at the line going into the carburetor.
If the rate of delivery is suspect, see if fuel is making it's way from the fuel tank, including through the fuel filter if there is one upstream of fuel pump, and through the hard line at the fuel pump inlet fitting.
If everything is fine at this point, it's time to dig into the carburetor.
The reason to leave the carburetor for last is that if you rebuild a perfectly fine carburetor first and do something wrong upon reassembly, and your real problem was caused by issues upstream of the carburetor, you will then have 2 problems at the same time.
That is worse scenario to ever have.
