The Honda 99101-ZG0-0450 Main Jet (#45) is a genuine OEM replacement designed for the F220 tiller. As a factory-sourced component, this jet carries Honda's exact sizing to maintain the correct air-fuel ratio the carburetor was calibrated for. Confirm your serial number against the fitment table before ordering, as Honda supersedes jet sizes at production breaks.
Key Features
- Exact OEM Calibration — the #45 size designation is a precise flow specification; this genuine Honda jet delivers the same metered fuel delivery as the original, keeping the carburetor running at the mixture the engine was tuned for.
- Direct OEM Replacement — sourced directly from Honda, this jet installs into the carburetor just as the original did, with no alterations needed.
- F220 Tiller Fitment — listed for the Honda F220 tiller; verify your serial number against the compatibility table to confirm this is the correct jet for your unit.
- Fuel Delivery Integrity — a worn or incorrect main jet disrupts the fuel-to-air ratio across the mid and upper throttle range, causing rough running, poor power output, or excessive fuel consumption.
The main jet is a precisely drilled orifice seated inside the carburetor bowl. Fuel drawn from the bowl passes through the jet, and its bore diameter determines exactly how much fuel enters the airstream at mid to wide-open throttle. Because the hole size is fixed and calibrated to the engine's displacement and intended load, even a small deviation — from wear, damage, or an incorrect replacement — shifts the mixture lean or rich and degrades performance. Replacing a worn or damaged jet with a genuine Honda part number 99101-ZG0-0450 restores the factory fuel metering the F220's carburetor depends on.
