The Multiquip 16033K4960 Main Jet is a genuine OEM component designed for the C30HDN concrete pump. Sourced directly from Multiquip, this main jet meets the exact specifications required to maintain proper fuel-air mixture delivery in the carburetor. It is a direct OEM replacement for C30HDN machines, ensuring the engine receives the correct fuel flow for consistent operation under load.
Key Features
- Genuine OEM Fuel Metering Accuracy — Calibrated to the precise orifice size required for correct fuel delivery in the C30HDN carburetor, maintaining the correct air-fuel ratio at all throttle positions.
- Direct Carburetor Fit — Threads directly into the carburetor body of the C30HDN without modification, restoring the original fuel circuit.
- Confirmed C30HDN Fitment — Verified for Multiquip C30HDN concrete pump applications, taking the guesswork out of parts sourcing.
- Engine Performance Restoration — A worn or clogged main jet causes rough running, lean hesitation, and loss of power under pumping load; replacing it with a correctly sized OEM jet restores full engine output.
- Fuel System Integrity — Using the correct OEM jet size prevents over-fueling or lean conditions that can lead to engine damage or erratic pump performance on the jobsite.
The main jet is a small but critical component located inside the carburetor's fuel bowl. It meters the precise amount of fuel delivered to the engine during mid-range and high-throttle operation, directly controlling the air-fuel mixture that determines how the engine runs under load. When the main jet becomes clogged, corroded, or worn, the engine will run rough, lose power, or stall — symptoms that can be mistaken for larger mechanical issues. Replacing a faulty main jet with the correct OEM part is one of the most effective first steps in restoring full carburetor and engine function.
