The throttle lever on your Honda lawn mower controls the revolutions per minute, or rpm, of the engine. The throttle lever is connected to a cable that runs to your carburetor. Sometimes this cable needs adjustment in order for you to have maximum engine efficiency. An engine that runs too fast will burn too much fuel and the lifespan will be shortened. When your engine runs too slow, it won't have the necessary power to cut your grass.
