Question

Answer
Hi Donna,

The carb most likely has dirt, debris or gummed fuel inside.  You will need to remove the carb, disassemble it, clean all the small internal openings and blow it out with compressed air.   Probe each and every hole with a small wire.   Adding a carb rebuild kit wouldn't hurt either.  
I don't have a diagram but if you keep every part in order as you disassemble it, you should be able to re-assemble without a problem.

Another thing to check is the gas cap, to make sure it is venting and not causing a vacuum in the tank.  Also check for water in the fuel.  

Let me know how you make out.
