Makita *METERING DIAPHRAGM ASSY EH76 - 5316005250
168767-7 supersedes older part numbers: WJ00009599, 5316005250
Original Makita metering diaphragm assembly (part 168767-7). This molded diaphragm restores the carburetor’s metering circuit—regulating fuel flow between idle and full throttle to cure hard starting, poor idle, bogging or surging caused by a hardened or torn diaphragm.
Built to Makita specification from fuel-resistant elastomer and compatible molded components, the assembly installs in the carburetor housing and is supplied as a single replacement piece. It’s designed to resist modern pump petrol blends and to match the original sealing surfaces for reliable throttle response.
Compatible models : RBC260, RBC230, RBC251, RBC310 (and related RBC series hand-held engines), EH760 and EH561 hedge-trimmer. Use these examples to cross-check your model’s parts diagram—this part appears across Makita two-stroke trimmers, blowers and hedge trimmers.
If your engine shows bogging, surging, or a change in throttle behavior after long service or exposure to ethanol fuels, replacing the 168767-7 metering diaphragm with this original Makita part is the direct repair to restore correct fuel metering and smooth operation.
