The Multiquip 99101ZG00550 Main Jet #55 is a genuine OEM carburetor main jet designed for a wide range of Multiquip equipment, including BP-25H backpack vibrators, MT-65H and MTX60HF/MTX70HF rammers, MC3SE and MC3H portable mixers, and C-4 walk-behind trowels. As an authentic Multiquip OEM component, the part is manufactured to the exact specification of the original part it replaces, ensuring a direct, no-guesswork installation into the carburetor bore. Sourced directly through authorized channels, this jet is the correct choice when restoring proper fuel delivery to your equipment.
Key Features
- OEM-Calibrated Fuel Metering — Manufactured to the precise #55 orifice size required for correct air-fuel ratio across the full throttle range.
- Direct Carburetor Drop-In — Threads directly into the carburetor body with OEM-matched dimensions, eliminating fitment guesswork during installation.
- Broad Equipment Compatibility — Fits BP-25H, MT-65H, MTX60HF, MTX70HF, MC3SE, MC3H, and C-4 models, making it a useful stocking part across multiple machine types.
- Restores Consistent Engine Performance — A worn or clogged main jet causes rich or lean running, rough idle, and loss of power; replacing it with the correct OEM jet restores stable combustion and consistent RPM.
- Fuel System Integrity — Proper jet sizing is critical to safe, stable engine operation — an incorrect jet can cause dangerous lean-running conditions or uncontrolled engine behavior.
The main jet is a small but critical component inside the carburetor that meters the precise volume of fuel delivered to the engine under load. It works by allowing a calibrated amount of fuel to pass through a fixed orifice, where it mixes with incoming air before entering the combustion chamber. When a main jet becomes clogged, worn, or is replaced with an incorrect size, the engine may run rough, lose power, run excessively hot, or fail to reach operating speed — all of which affect productivity and can lead to premature engine wear.
