The Honda 28400-ZH8-033ZM is a genuine OEM Recoil Starter Assembly (Loosy Gray) designed for the GX120 horizontal shaft engine. As a direct Honda OEM component, it is manufactured to the same specifications as the original unit installed at the factory. This assembly is the Loosy Gray color variant — confirm that this color matches your existing starter before ordering, as GX120 engines may have been fitted with different color variants depending on production run. Always verify your engine's serial number against the fitment table to ensure this is the correct assembly for your unit.
Key Features
- Genuine Honda OEM Assembly — sourced directly from Honda, this starter assembly carries the correct rope pulley geometry, pawl configuration, and spring tension specified for the GX120 engine, so you're not chasing a sloppy engagement or a failed return.
- Color-Variant Accuracy — supplied in Loosy Gray to match the original starter housing on compatible GX120 builds; confirm the color against your existing assembly before purchasing.
- Complete Recoil Unit — this is a full starter assembly, not individual components, making replacement straightforward without sourcing separate springs, pulleys, or housings.
- Serial Number Verification Recommended — Honda updates and supersedes starter assemblies at production serial breaks; check your GX120 serial number against the fitment table to confirm this is the right assembly for your engine.
The recoil starter assembly is the manual pull-start mechanism on the GX120 horizontal shaft engine. When the operator pulls the starter rope, a coiled return spring inside the assembly winds and retracts the rope, while a set of pawls engages the engine's flywheel cup to crank the engine over for starting. When the engine fires, the pawls disengage automatically, protecting the starter from back-spin. Over time, the return spring can fatigue and lose tension, the rope can fray or break, and the pawls can wear or stick — any of these failures leaves the engine unable to start. Replacing the full assembly restores reliable hand-start operation and gets the GX120 back to work.
