  If your Westfalia Chainsaw engine won't start, it could be due to several reasons: * **No spark:** Ensure the spark plug is clean. If the electrodes are burned or worn, replace it. Check the spark plug gap with a feeler gauge and test for spark using a spark tester. * **No fuel:** Pump the primer bulb. If no fuel flows, the pipes are blocked and the machine needs servicing. If the spark plug is wet, the engine may be flooded. * **Flooded engine:** Remove the spark plug, turn the engine upside down, pull the choke, and pull the starter handle approximately 10 times. Then, clean and refit the spark plug. * **Incorrect fuel/oil mix:** Drain the current mix and use the correct fuel mix.
