The Wacker Neuson Carburetor Complete is a genuine OEM replacement designed for WP1540A and WP1550A series single-direction vibratory plate compactors. Sourced directly from Wacker Neuson, this carburetor complete carries the same part specifications as the unit installed at the factory, so you can be confident in a correct, straightforward swap. Fitment covers the WP1540A, WP1540Aw, WP1550A, and WP1550Aw — including the WP1550Aw Sunbelt configuration — making the go-to replacement across the full WP15 plate compactor family.
Key Features
- OEM-Spec Fuel Metering: — Calibrated to the exact air/fuel mixture ratio specified for the WP15 series engine, ensuring consistent throttle response and smooth idle under load.
- Drop-In Replacement: — Matches all mounting bolt patterns, fuel line connections, and choke linkage positions of the original carburetor, so no fabrication or adaptation is needed during installation.
- Broad WP15 Family Coverage: — Fits WP1540A, WP1540Aw, WP1550A, and WP1550Aw models, including the Sunbelt-configured WP1550Aw variant.
- Restored Engine Performance: — A fresh carburetor complete eliminates hard starting, rough running, and loss of compaction force caused by worn needle seats, clogged jets, or degraded float assemblies.
- Fuel System Integrity: — Genuine OEM construction maintains correct fuel delivery and prevents unmetered fuel from entering the crankcase — critical for protecting the engine during high-cycle compaction work.
The carburetor is responsible for mixing air and fuel in the precise ratio the engine needs to start reliably and run efficiently under varying load conditions. On a vibratory plate compactor like the WP1540A or WP1550A, the engine operates under constant vibration and frequent throttle changes, which accelerates wear on internal carburetor components such as the float, needle valve, and emulsion jets. When the carburetor degrades, symptoms typically include hard cold starts, erratic engine speed, excessive fuel consumption, or the engine stalling under load — all of which directly reduce compaction output on the job.
