Answer
Hi Ronnie,

Check the fuel cap to make sure it is venting.  
I suspect a fuel flow problem.  Check the carb's float and adjust it so the float is set closer to the needle valve.  Make sure you have a good fuel flow from the fuel tank.  If no change, you may need to disassemble the carb and clean it of any dirt.

Let me know how you make out.
Michael
