Make sure the filter is clean, most are washable in water. The L adjustment adjusts low speed, the H the high speed. Screw both fully in and screw them both out 1 1/4 turns. Start the machine and adjust L for the highest idle speed, adjust the idle speed until the chain doesnt turn and the saw sounds right and adjust the H setting until a slight burbling is heard at full tilt and not at the most revvy setting. This allows for a slightly rich mixture that protects the engine from seizure and over revving.
