The Multiquip 99101ZH70680 Main Jet #68 is a genuine OEM carburetor jet designed for a wide range of Multiquip equipment including MS15H5.5, MS15E, MS18H5.5, MS18H8, MS18E, MS45H5.5, MS45E, MS-63, and walk-behind trowel families including the J-SERIES, JA-SERIES, and EPOXY-SERIES. As a direct OEM replacement, this jet is manufactured to the same specification as the original component, ensuring the correct fuel metering your engine depends on. Sourced directly through authorized Multiquip supply channels, 99101ZH70680 is the part number to specify when restoring carburetor performance across these equipment lines.
Key Features
- Correct Fuel Metering Orifice — Sized at #68 to deliver the precise fuel flow the carburetor circuit requires, maintaining the correct air-fuel ratio under load.
- Genuine OEM Component — Manufactured to Multiquip's original specification, this jet matches the bore diameter and thread pitch of the factory-installed part for a drop-in installation.
- Broad Equipment Compatibility — Fits MS15H5.5, MS15E, MS18H5.5, MS18H8, MS18E, MS45H5.5, MS45E, MS-63, J-SERIES, JA-SERIES, and EPOXY-SERIES machines.
- Restored Engine Response — A clogged or damaged main jet causes rough running, hesitation under load, and hard starting; replacing it with this part restores crisp throttle response and stable idle.
- Fuel System Integrity — Using the correct OEM jet size prevents over-fueling or lean conditions that can damage cylinder walls and valves over time, protecting the long-term health of the engine.
The main jet is a small but critical component inside the carburetor's fuel circuit. It controls the volume of fuel delivered to the engine at mid-to-full throttle by metering flow through a precisely sized orifice. When the jet becomes clogged with varnish or debris — or is worn beyond its rated bore — the engine loses power, runs rich or lean, and may refuse to start. Replacing the main jet with the correct OEM-specified #68 size restores the carburetor to its designed fuel delivery curve, keeping the engine running at its intended output.
