Key Features
- Genuine OEM Fuel Metering Precision — Calibrated to the exact flow rate and jet sizing specified for Honda-carbureted Multiquip engines, maintaining correct air-fuel ratio across the RPM range.
- Drop-In Carburetor Replacement — Matches the original thread pitch, jet diameter, and seat profile for straightforward installation into the carburetor body without rework.
- Broad Verified Fitment — Compatible with MC94, MC64, WM70, R2000H, QP402H, QP3TH, MP25 through MP2090 masonry saw series, and MVH304GSB plate compactor.
- Consistent Engine Performance — A correctly sized main injector keeps fuel delivery consistent under load, preventing rough running, black smoke, or lean surge that a worn or incorrect jet causes.
- Fuel System Safety — An OEM-spec injector with proper seating and thread integrity reduces the risk of fuel weepage inside the carburetor bowl, a relevant concern on engine-powered equipment operating near flammable materials.
The main injector — also known as the main jet — is the primary fuel metering component inside the carburetor. It controls how much fuel enters the engine under mid-to-full throttle conditions by restricting fuel flow through a precisely sized orifice. When this jet becomes clogged with varnish or debris, the engine runs lean, loses power, and may overheat; if the orifice is worn or the wrong size is installed, the engine runs rich, wastes fuel, and produces excess emissions. Replacing it with the correct OEM-spec part restores the fuel delivery the engine was designed to operate on.
