The Honda 99101-124-0650 Main Jet (#65) is a genuine OEM carburetor jet designed for a wide range of Honda engines, generators, lawn mowers, water pumps, tillers, and snow blowers. This #65-size jet is the factory-specified fuel metering component for carburetors across Honda's G, GC, GCV, GS, GSV, GV, GX, and GXV engine series, as well as many Honda power equipment units including the E1500, EB2200, EB2500, and other generator models. Because Honda supersedes carburetor jets at serial breaks and across model variants, always confirm part number 99101-124-0650 against your machine's serial number using the fitment table before ordering. As an authentic Honda OEM part, this jet ships to the exact specification your carburetor was built around — no guesswork on sizing.
Key Features
- OEM Fuel Metering Accuracy — drilled to the precise #65 orifice diameter Honda specifies, ensuring the correct air-fuel mixture for clean starting, stable idle, and full-throttle power across all covered applications.
- Broad Honda Fitment — listed for Honda horizontal and vertical shaft engines including the G150, G200, GC135, GC160, GC190, GCV160, GCV170, GCV190, GCV200, GS160, GS190, GSV190, GV150, GV200, GX140, GXV120, and GXV160, plus generators, lawn mowers, water pumps, tillers, and snow blowers — see the fitment table for the complete model list.
- Serial Number Verification Matters — Honda issues replacement jets by serial range; check your machine's serial number against the fitment table to confirm this is the correct jet for your unit before installing.
- Direct Carburetor Replacement — this jet installs directly into the main jet port of the compatible Honda carburetor with no alteration required, restoring the factory fuel circuit in a straightforward service procedure.
- Prevents Rich or Lean Running — a worn, corroded, or incorrectly sized main jet causes hard starting, rough running, excessive fuel consumption, or power loss; replacing it with the correct OEM jet restores crisp throttle response and consistent output.
The main jet is the small, precisely sized brass orifice inside the carburetor that meters the volume of fuel delivered to the engine under load. At mid to full throttle, fuel is drawn through this jet and mixed with incoming air to form the combustible charge the engine needs to produce power. The diameter of the jet's bore is calibrated to the engine's displacement and intended operating range — even a minor deviation in size will cause the mixture to run too rich or too lean, degrading performance and potentially damaging the engine over time. When a main jet becomes clogged with varnish deposits from stale fuel, or wears and distorts over extended service, the engine may surge, hesitate, lose power, or refuse to run at full throttle; fitting a fresh OEM jet restores accurate fuel delivery and returns the carburetor to its designed operating state.
