Why won't my Rockwell RS8020 Brush Cutter engine start?

  Your Rockwell Brush Cutter engine might not start due to several reasons. First, check if the ON/OFF switch is in the STOP position and turn it to the I position. If the engine is cold, ensure the choke is OFF. Also, make sure you have enough fuel and prime the carburetor. If the fuel is old, drain and refuel with a fresh mix. Finally, inspect the spark plug for faults or clogging, and check the spark plug gap. Replace or repair any faulty components as needed.

  If your Rockwell Brush Cutter is experiencing low power or the engine speed isn’t increasing, there are several potential causes. Check the air filter for dirt or clogs and clean or replace it. Inspect the fuel filter and replace it if necessary. Also, ensure that grass isn't wrapped around the output shaft or cutting attachment; if it is, move the ON/OFF switch to the STOP position, disconnect the spark plug cap, and remove the grass. If the idle speed is too low, adjust the idle screw.
