Why Wacker Neuson Vibratory rammer & tamper engine does not accelerate?
- WWilliam AndersonSep 9, 2025
If your Wacker Neuson vibratory rammer & tamper engine isn't accelerating properly or is running poorly, consider these potential causes: dirty air filters (clean or replace them), too much oil in the fuel (drain the tank and refill with new mixed fuel), a fouled or incorrect spark plug (clean, replace, and ensure it's a resistor-type), a dirty muffler or exhaust port (clean them), an incorrect fuel mixture adjustment (adjust the screw and clean the fuel jets), or an air leak in the carburetor system (check all connections). For leaking crankshaft seals, consult the WM 80, WM 90, or Yanmar Engine Repair Manual.
