The Honda 99101-ZH7-0750 Main Jet (#75) is a genuine OEM carburetor component listed for a wide range of Honda engines, generators, outboards, and power equipment — including GX160 and GX200 horizontal shaft engines, BF4, BF5, BF6, and BF50 outboard motors, EB2200, EB2500, EM1600, EM1800, EM2200, and EM2500 generators, and the HS624 two-stage snow blower. Because this main jet carries a size designation — #75 — and the same part number appears across multiple distinct machine types, confirm that #75 is the correct jet size for your specific unit before ordering. Sourcing directly from Honda ensures the jet is produced to the exact tolerances the carburetor was engineered around, giving you confidence the fit and flow characteristics are correct.
Key Features
- Correct Fuel Metering — the #75 size designation governs the fuel flow rate through the carburetor; an incorrect jet size will cause rich or lean running, so matching this number to your carburetor specification is essential
- Genuine OEM Part — manufactured by Honda to the same tolerances as the original, ensuring the orifice diameter is consistent and the carburetor performs as designed
- Broad Fitment Listing — this part number is listed for GX160 and GX200 horizontal shaft engines, BF4, BF5, BF6, and BF50 portable outboard motors, multiple EB and EM generator models, and the HS624 two-stage snow blower; verify your model and carburetor type before ordering
- Serial Number Verification Recommended — Honda supersedes carburetor jets at serial breaks across many of these models; check the serial number on your machine against the fitment table to confirm part number 99101-ZH7-0750 is current for your unit
The main jet is a precisely sized orifice fitted inside the carburetor body that meters the fuel delivered to the engine under normal operating load. The diameter of the jet's bore is calibrated to produce the correct air-to-fuel ratio at cruise and full throttle — too large and the engine runs rich and sooty; too small and it runs lean and hot. When a main jet becomes clogged with varnish deposits or is damaged, the engine will typically stumble under load, surge, or refuse to reach full power, and replacing it with the correct OEM jet restores proper fuel delivery.
