# Check the fuel level. If the fuel tank has run dry, refill the tank. To start the engine, press the fuel pump bulb at least five times to ensure proper fuel flow.

Check if the engine is flooded. Pull off the spark plug boot. Unscrew and dry off the spark plug. Set slide control to O. Open the throttle wide. Crank the engine several times with the starter to clear the combustion chamber. Refit the spark plug. Connect the spark plug boot. Set the slide control and the choke lever. Start the engine.

Check the spark plug. If fouled, clean it. Check to ensure that the spark plug is gapped properly. If damaged, replace it. Check for and fix any problems, such as too much oil in the fuel mix or a dirty air filter that will cause continued fouling and fix it.

Check the air filter. First, press in the tab on the air filter cover and remove it. Remove the felt and foam filter elements. Clean or replace the elements. Replace the elements and refit the filter cover.

Check the spark arresting screen inside the muffler. Be sure to wait for the engine to cool before performing this work. Remove the spark shroud by remove it's screw and remove the spark arresting screen. Clean the spark arresting screen, if necessary. Replace the screen, if damaged. Refit the spark arresting screen and shroud.

Check the fuel pick up body within the fuel tank. If dirty, the use a toothbrush to clean it. If damaged, replace the filter.
Engine Stalls at Idle
# Adjust the carburetor. Warm up the engine first. Carefully turn the low speed screw, which is the upper screw on the carburetor near the choke lever, until it is completely seated. Open the screw one turn counterclockwise. Turn the idle speed screw, below the low speed screw, slowly counterclockwise until the blades begin to move when the engine is idling. Turn the idle speed screw counterclockwise one turn.
Engine Idles Too Quickly
# When the engine idles too quickly, the blades will be moving at idle. Adjust the carburetor by turning the idle speed screw slowly counterclockwise until the cutting blades stop running, then turn the screw counterclockwise again one half turn.

Check the exhaust filter. They have a tendancy to stop up. Won't run off idle. It should unsrew. It's actually the spark arrester
