About this kit

The PB-2520 is a light, high-revving handheld blower, and it hates old gas. A carburetor that sat half full over the winter will usually need replacing rather than cleaning. Ours replaces Echo A021004700, A021000722 and A021000723 and arrives factory tuned.

Three fuel lines means you replace the pickup, the return and the bulb line together, and the vent keeps the tank from pulling a vacuum. The air filter matches Echo A226002160.
