The Wacker Neuson Main Jet is a genuine OEM component designed for a wide range of Wacker Neuson equipment, including CT48 concrete power trowels, GP3800, GP5600A, GP6600A, GPS5600A, and GPS6600A portable generators, GV5600A and GV6600A value generators, GPS9700A generators, BPU 5545A, BPU5260Ah, and BPU6275Ah reversible vibratory plate compactors, the BFS 1318AS floor saw, and the RD7A tandem roller. As a genuine Wacker Neuson OEM part, the is manufactured to the same specification as the original component, ensuring a direct, reliable fit with no guesswork. This main jet is a critical carburetor component — correct sizing is non-negotiable for consistent engine performance across every machine in this broad fitment range. Keep a spare on hand for any of these models and avoid unnecessary engine troubleshooting in the field.
Key Features
- Genuine OEM Fuel Metering Accuracy — Manufactured to exact orifice sizing specifications, ensuring the correct air-to-fuel ratio is maintained across the full throttle range.
- Direct Carburetor Drop-In — Threaded to OEM dimensions for straightforward installation into the original carburetor body without adaptation or rework.
- Broad Fitment Coverage — Fits CT48 trowels, GP/GPS/GV generator families (3800–9700 series), BPU 5545A, BPU5260Ah, BPU6275Ah plate compactors, BFS 1318AS floor saw, and RD7A tandem roller.
- Consistent Engine Power Output — A correctly sized main jet keeps the engine running at rated power; a worn or partially blocked jet causes rich or lean running, rough idle, and loss of output under load.
- Fuel System Integrity — Using the OEM-specified jet prevents unmetered fuel delivery that can wash cylinder walls, foul spark plugs, or cause engine damage over time.
The main jet is a precisely sized orifice fitted inside the carburetor that controls how much fuel enters the engine at mid-to-full throttle. Fuel is drawn through this jet and mixed with incoming air before combustion — the jet's orifice diameter determines the fuel flow rate, so even a small variation in size or a partial blockage causes the engine to run too lean or too rich. A worn, corroded, or clogged main jet typically presents as hard starting, surging, loss of power under load, or excessive fuel consumption, and replacing it with an OEM-specification part restores correct fuel metering and stable engine operation.
