Weedeater SST25 Trimmer Head Spins when Idle

From: Paul F.
Subject: Weedeater SST25
Hi, I had called a weed eater rep about the SST25 I had just bought and was told that the trimmer head should stop when machine was throttled down. Mine didn’t do this so I brought it back and got a new machine but the head still spins quite fast at idle. Is this normal? Paul

Hi Paul,
it’s not normal, but you can fix it by adjusting the carburetor. Since the carburetor controls the spinning speed of trimmer while idle, screwing/unscrewing a tiny screw on it will change the weedeater’s speed. Carburetor is usually located near the air filter or muffler.
