Original Makita 957150040 — carburetor control parts kit. This genuine Makita repair set contains the small control components used inside the carburetor (pump/diaphragm control pieces, linkages, springs, seals and related small parts) so you can restore proper fuel/air metering and choke/pump action without replacing the whole carburetor. It’s a direct-fit Makita part listed as the carburetor control/repair set for a number of two-stroke chainsaw and brushcutter models.
Example Makita models that reference part 957150040: DCS400, DCS430, DBC4500 and DBC4510. Use the part number on your tool’s parts diagram to confirm fit before installation.
Supplied as the carburetor control-parts kit — ideal if you need to replace the small, wear-prone elements that cause hard starting, poor idling or inconsistent throttle response.
