REPAIR GUIDE

Step by step

  1. 1
    Drain the tank
    Outside, with the engine cold, siphon or dump the old fuel into a can. Old petrol smells sour and looks dark.
  2. 2
    Run the carb dry
    Start it if you can, or loosen the bowl drain if it has one, so stale fuel leaves the carburetor too.
  3. 3
    Refill with fresh fuel
    Use petrol less than 30 days old. Prime if the mower has a bulb, then pull.
