Why Maintain Your Carburetor?

The carburetor is the heart of your small engine's fuel system. Over time, fuel deposits, worn gaskets, and cracked primer bulbs can cause hard starts, rough idling, and reduced cutting power. A full service kit like this restores your trimmer to like-new performance without the expense of a professional repair.
