The fuel pump is located, when looking at your engine w/ hood up,on the left (passenger) side of the engine, towards the front of the engine. You could follow the gas lines from your carb to the pump.
The pump is only about $15. Take the lines off, and two bolts, she comes off. Don't lose the rod inside.
It sounds like the fuel pump. An easy way to check it is take the line off at the carb. point the line into a jar. Have someone crank the engine and see how much gas comes out. It should fill up quite quickly.
If pumps checks out ok, it could be the float inside the carb. If the float sticks up, it will not allow gas to come into the bowl. Take a hammer and slightly tap around where the gas line comes in. When to bowl is empty, the float should come down, opening the needle to allow gas to come in.
Just an idea.
