The Honda 28442-Z0H-003 Recoil Starter Spring is a genuine OEM replacement designed for GX25, GX35, and GX50 horizontal shaft engines, the FG110 tiller, HHT25, HHT35, UMC425, and UMC435 trimmers, and the WX10 water pump. As an authentic Honda part, this spring is manufactured to the same specification as the original, ensuring it winds, tensions, and releases exactly as the starter system requires. Confirm your unit's serial number against the fitment table before ordering, as Honda supersedes components at specific serial breaks across this range.
Key Features
- Genuine OEM Winding Tension — manufactured by Honda to deliver the correct recoil tension for crisp, consistent rope retraction on every pull
- Direct Replacement — engineered to swap in without modification, restoring the starter assembly to its original operating condition
- Broad Fitment — covers GX25, GX35, and GX50 horizontal shaft engines, the FG110 tiller, HHT25, HHT35, UMC425, and UMC435 trimmers, and the WX10 water pump; verify by serial number using the fitment table
- Restores Starting Reliability — a fatigued or broken recoil spring causes the rope to fail to retract or leaves the starter unable to build the tension needed to spin the engine over; replacing it brings the starter back to full function
The recoil starter spring is the coiled flat spring housed inside the starter cup that stores energy as the operator pulls the starter rope and then releases it to retract the rope back into position for the next pull. Without the correct spring tension, the rope either fails to return fully or snaps back too weakly to engage the flywheel pawls, making the engine impossible to start. A broken or deformed spring must be replaced promptly, as no amount of pulling will turn the engine over once the spring loses its ability to hold and release tension.
