Do you have one of these? It is the Primer Solenoid. If so, the lever should be inline with the primer body during normal operation (As is shown in the picture). If yours is leaking fuel, you can buy replacement caps cheap..

Also, if the motor will run at higher speeds while you pump the fuel primer bulb, then it's a good bet the fuel pump is shot..
