The Wacker Neuson Idle Mixture Kit is a genuine OEM component designed for PTS4V and PTS4V(I) series heavy-duty trash pumps. Sourced directly from Wacker Neuson, this kit delivers the exact tolerances and calibration required to restore proper fuel-to-air mixture at idle. It is a direct-fit replacement that installs to the original specification with no additional modification. If your PTS4V or PTS4V(I) is hunting at idle, running rough at low throttle, or stalling under light load, replacing the idle mixture components with part number is the correct first step toward restoring consistent, stable engine performance.
Key Features
- OEM-Calibrated Mixture Specs — Engineered to Wacker Neuson's precise fuel-to-air ratio requirements for the carburetor's idle circuit, ensuring the engine settles at the correct RPM without hunting or surging.
- Direct Carburetor Fit — Components thread and seat into the existing carburetor ports on the PTS4V and PTS4V(I) exactly as the originals, making installation straightforward for any experienced technician.
- Confirmed PTS4V and PTS4V(I) Compatibility — Verified fitment for both the standard PTS4V and the industrial PTS4V(I) heavy-duty self-priming trash pump models.
- Restores Stable Idle and Low-Speed Throttle Response — A worn or damaged idle mixture circuit causes rough running, hard starting, and stalling at low load; replacing this kit brings the engine back to clean, responsive operation.
- Genuine Wacker Neuson OEM Part — Supplied as an authentic Wacker Neuson replacement kit, so you get the same components that left the factory — not an approximation.
The idle mixture kit controls the ratio of fuel to air delivered through the carburetor's idle circuit, which governs engine behavior at low throttle and during warm-up. When these components wear, corrode, or become clogged with residue, the engine loses the ability to maintain a steady idle — resulting in rough running, stalling, or difficulty starting. Replacing the idle mixture kit recalibrates the fuel delivery at low speed and restores the stable, consistent idle that a trash pump like the PTS4V depends on for reliable priming and continuous operation on the jobsite.
