Remove the fuel line from the carb. Put the end in a container. With the ignition off, pull the rope a few times. Does any fuel come out? If not, start working back until you find the the problem. It could be the fuel pump, a clogged fuel filter, or a collapsed or missing inlet hose or filter in the tank. Does it have a gas shut off? If so, is it on? (That happens. Don't ask how I know.
If you have a syringe, you can also prefill the carb to make sure you are starting with a full carb. It takes a bunch of cranks to get the fuel bowl full sometimes.
If gas is getting to the carb, check the float bowl inlet needle/seat, if it's corroded and stuck closed, no gas will get in. Check float height as well.
If it's got spark and sputters a bit, it's almost always fuel related...
Good luck and Welcome to the Forum!
