The Wacker Neuson Idle Jet is a genuine OEM component designed for a wide range of Wacker Neuson equipment, including PT2 trash pumps, CT36-6 concrete trowels, GP2600 portable generators, PDT2 and PDT3 diaphragm pumps, PG2 and PG3 dewatering pumps, and the extensive VP and WP series single-direction vibratory plate compactors. Sourced directly from Wacker Neuson, this idle jet meets the exact engineering specifications of the original part — no guesswork, no substitutions. It is a direct fit for the carburetor assemblies found across this broad equipment lineup, covering compaction, pumping, power generation, and concrete finishing applications. Whether you are servicing a VP1340, VP1550, WP1540, WP1550, or any of the other compatible models, part number is the correct replacement.
Key Features
- Correct Fuel Metering at Idle: — Precisely sized orifice matches OEM carburetor specifications, ensuring the engine receives the right air-fuel mixture at low RPM for smooth, stable idle across all compatible models.
- Genuine OEM Part: — Manufactured to Wacker Neuson's original design standards — same material, same dimensions, same orifice calibration as the part that came in the machine from the factory.
- Broad Cross-Equipment Compatibility: — A single part number covering VP and WP vibratory plate compactors, PT2 and PDT trash and diaphragm pumps, PG dewatering pumps, CT36-6 trowels, and GP2600 generators simplifies parts inventory for mixed fleets.
- Direct Carburetor Drop-In: — Threads directly into the carburetor body on compatible small engines; no re-jetting, re-sizing, or adaptation required for a confirmed fitment application.
- Protects Engine Health: — A worn or clogged idle jet causes rough idling, hard starting, and lean-run conditions that accelerate wear on internal engine components; replacing it restores proper fuel delivery before secondary damage occurs.
- Fuel System Safety: — A correctly installed, OEM-spec idle jet maintains proper fuel circuit sealing within the carburetor, reducing the risk of fuel leaks or uncontrolled flooding at the idle circuit.
The idle jet is a small but critical brass metering component housed inside the carburetor. Its precisely drilled orifice controls the volume of fuel delivered to the engine during low-speed and idle operation — when the throttle is nearly closed and the main jet plays little role. If the idle jet becomes clogged with varnish, debris, or ethanol residue, the engine will idle roughly, stall at low speed, or refuse to start without repeated throttle input. Replacing a faulty idle jet restores the correct air-fuel ratio at idle, which is essential for consistent warm-up behavior, smooth low-load operation, and dependable starts across pumps, compactors, trowels, and generators alike.
