      If your Craftsman Trimmer engine won't start, there are several potential causes: * The fuel tank may be empty; if so, fill it with fuel. * The primer bulb may not have been pressed enough; press it fully and slowly 10 times. * The fuel may be old; drain the gas tank and add fresh fuel. * The spark plug may be fouled; replace or clean it. * The spark arrestor may be plugged; clean or replace it.
