About this kit

Husqvarna's 28cc handheld is one of the best-selling homeowner blowers, and the C1Q-W37 carb on it is famous for going lean after a season of ethanol fuel. Our replacement matches Husqvarna 590460102 and 545081811 and comes with the 545112101 air filter and the 545081841 fuel line kit.

The Jonsered B2126 and BV2126 are the same machine under a different name, and they take the same carb. Both options fit identically; the first one is the fuller bag.
