About this kit

Echo's 210-series engines ran for years on the Zama RB-K75, and plenty of them are still running on the original. When the trimmer needs full choke to stay alive, or the bulb fills but the engine will not catch, a fresh RB-K75 pattern carb brings it back without chasing jets and diaphragms.

The same body also sits on Echo's HC-150 and HC-151 hedge trimmers, PE-200 edgers and PPF-210 pruners, so one kit covers a whole family of tools. You get new gaskets, two bulbs, a plug, a filter and three pieces of line — everything that has aged at the same pace as the carb.
