The Wacker Neuson Main Jet #90 is a genuine OEM carburetor component designed for CT48 series walk-behind concrete power trowels and RS800A/RSS800A single-drum vibratory rollers. As a direct Wacker Neuson OEM part, the is manufactured to the same specification as the original, ensuring correct fuel metering for the engine it serves. This jet is confirmed to fit multiple CT48 variants — including AGP, AGT, AVP, and AVT configurations — as well as both the RS800A and RSS800A roller models.
Key Features
- Calibrated Fuel Metering: — Sized at #90, this jet delivers the precise orifice diameter required for correct air-fuel mixture at the carburetor, keeping the engine running at the intended power output.
- Genuine OEM Construction: — Sourced directly from Wacker Neuson, the 5000110615 is produced to the same material and dimensional standards as the part it replaces, with no guesswork on sizing or thread spec.
- Broad CT48 Family Coverage: — Fits CT48AGP, CT48AGT, CT48AVP, CT48AVT, and their CE and E-suffix variants, covering a wide range of 48-inch walk-behind concrete trowel configurations.
- Roller Compatibility: — Also fits the RS800A and RSS800A single-drum vibratory rollers, making this a shared service part across multiple Wacker Neuson machine families.
- Fuel System Integrity: — A worn or incorrectly sized main jet causes rich or lean running conditions, leading to power loss, hard starting, and excessive fuel consumption. Replacing with the correct #90 OEM jet restores proper carburetor function.
The main jet is one of the most critical calibration components inside a carburetor. It controls how much fuel is drawn into the venturi at mid-to-full throttle, directly influencing engine power, fuel efficiency, and exhaust emissions. A jet that is clogged, eroded, or wrong-sized shifts the fuel mixture out of specification — symptoms typically show up as bogging under load, rough idle, or black smoke from a rich condition. Replacing a failed or worn jet with the correct OEM-spec 5000110615 restores the carburetor's designed fuel delivery and brings engine performance back to standard.
