The Multiquip 99101ZG00580 Main Jet (#58) is a genuine OEM carburetor jet designed for MTX70HF, MTX60HF, and MTR40HF series rammers. As a direct Multiquip OEM part, it meets the original design specification for the float-carburetor fuel circuit used on these machines. Verified fitment covers the MTX70HF, MTX60HF, and MTR40HF rammers, so you can order with confidence knowing this is the correct jet size for your machine's carburetor.
Key Features
- Correct Jet Sizing for Float Carburetors — Calibrated to the #58 orifice specification, ensuring the proper air-to-fuel ratio for the float carburetor fitted to these rammer models.
- Genuine OEM Sourcing — Supplied directly through the Multiquip OEM parts program, so the part number, material, and orifice diameter match the original component exactly.
- Confirmed Rammer Fitment — Fits MTX70HF, MTX60HF, and MTR40HF rammers, all equipped with float-type carburetors requiring this specific main jet.
- Drop-In Carburetor Replacement — Threads directly into the main jet seat of the float carburetor with no modification to the carb body or fuel circuit required.
- Consistent Fuel Delivery Under Load — A worn or damaged main jet causes fuel starvation, rough running, or hard starting; replacing it with the correct #58 jet restores smooth, consistent combustion and full ramming force.
The main jet is the primary metering component inside the carburetor that controls how much fuel enters the engine under normal running load. It is a small precision-drilled orifice — in this case sized at #58 — through which fuel is drawn by engine vacuum and mixed with incoming air before combustion. If the jet becomes clogged, eroded, or damaged, fuel delivery is disrupted, leading to poor throttle response, loss of power, stalling under load, or difficulty starting. Replacing a worn main jet with the correct OEM-spec part restores proper fuel metering and returns the rammer to full operating performance.
