    Why does White 550 engine run erratically?
    • P
      perezmicheleJul 31, 2025
      An erratic engine in your White Snow Blower can stem from a few causes. Check if the unit is running on CHOKE and move the choke lever to the OFF position. A blocked fuel line or stale fuel could also be the culprit; clean the fuel line and refill with fresh fuel. Water or dirt in the fuel system can also cause issues; drain the fuel tank and carburetor, then refill with fresh fuel.
