Set the Featherlite 1500 on a flat surface. Disengage the starter switch into the "Off" position. Unhinge the rubber boot from the tip of the engine, on the side of the power head. Unscrew and remove the spark plug from the cylinder with socket wrench.
Check the spark plug's electrode tip for heavy carbon deposits or signs of damage. Replace the spark plug if necessary, by screwing a new one back into the cylinder hole. Attach the ignition tester to the rubber boot and to the tip of the spark plug.
Turn the ignition switch back into the "On" setting. Crank the starter rope firmly at least four times. Watch the ignition tester's window for a blue spark to jump across the points. Repair ignition system if the spark is yellow or absent during test.
Disconnect the ignition tester from the rubber boot and the spark plug. Take the spark plug out of the cylinder again. Screw the compression gauge finger tight into the cylinder hole.
Crank hard on the starter rope again until the gauge's needle stops increasing. Check the reading on the gauge. Repair the compression and air systems if the needle doesn't reach at least 90 psi, or lbs. per square inch.
Unscrew the air filter box from the side of the leaf blower's engine. Take the box off to access the carburetor. Unhook both fuel hoses from the carburetor with your fingers. Tilt the leaf blower over to the side and watch for gas to come out of the hoses. Repair the fuel system if no fuel emerges from the hoses, as it is being blocked from leaving the fuel tank either through a plugged fuel filter, or clogged fuel hoses.
