    • Fuel Pump Problems: Inadequate pressure or air leaks in fuel lines.
    Addressing these issues involves inspecting and servicing the fuel system components.
Troubleshooting Tips
  • Oscillating Axle Issues:
    • Inspect for visible damage or wear on axle components.
    • Check hydraulic lines for leaks or blockages.
    • Ensure the axle's range of motion is unobstructed.
  • Engine Performance Problems:
    • Replace the fuel filter if clogged.
    • Adjust the choke settings to the manufacturer's specifications.
    • Clean the carburetor and verify the fuel mixture.
    • Test the fuel pump for proper pressure and inspect for leaks.
