Since January! The fuel has probably varnished up and clogged the filter. You might try blowing out the fuel lines from the pump back to the tank, but I'd drain and dispose of the old fuel. You need to dose the tank with something like Stabil to keep the gas from going bad if you plan to let it sit like that. The old fuel in the carb bowl could have glued the float valve shut, too...
