Regularly cleaning or replacing the air filter and ensuring correct jetting can help maintain optimal performance.
Fueling or Intake Issues
Fuel leaks are another concern, often indicated by a strong fuel smell or visible leaks around the carburetor. This can happen due to worn gaskets or loose connections. Inspecting and replacing gaskets as needed can prevent leaks.
