Fuel pump. It may take a while to get the fuel from the tank to the carb. Run it for awhile with just the starting fluid and see if you can get the pump to pick up. If that doesn't work, take off the fuel line to the carb and turn it over to see if fuel is flowing. If so, your carb may need a rebuild. After 8 yrs it prolly will. Check the fuel filter too if it has one.
