Some simple things to start with:
You could have a venting issue with the tank, meaning the tank vents that are in the cap are stuck and not allowing the tank to vent. That will build a vacuum in the tank and not let the gas out. You can check for that by running with the filler cap open. If it runs OK with the filler cap open, you may need to attend to the vents.
The petcock is vacuum operated and the vacuum valve may have gone south. You can test for that by disconnecting the fuel hose and directing it into a container, then apply a vacuum to the petcock's vacuum line. That is best done with a separate length of hose that you can suck on. If gas doesn't flow from the petcock in a good solid stream, suspect the petcock. Either rebuild or replace. If a replacement is needed, consider a non-vacuum petcock like the Raptor 660.
The carburetor's inlet valve may be stuck or sticky. This is harder to diagnose without some way to provide constant vacuum to the petcock, but what you should try and do is open the drain at the bottom of the carb and see that fuel comes out. If it doesn't, rap on the side of the carb bowl with a screwdriver handle; that may allow the valve to open and fuel to flow. The fix there is to remove the bowl and float assembly and refresh the valve needle.
If the above seem all OK, you may have an ignition issue.
