Troubleshooting - Wildland Pump Operations - MARK-3® Watson Edition

If the pump won't start or is running rough, check the following basic troubleshooting steps:
Ensure that the fuel line is clear of air bubbles or contamination.

Make sure that there is a spark.
When checking the spark, make note of the colour of the spark plug. If the air-fuel mixture is too lean the spark plug is white and if it's too rich the spark plug is black.

Keeping a clean air filter will ensure good flow of oxygen into the carburetor.

Remove the pump end and inspect to ensure there is no blockage. When reattaching the pump end, use only finger pressure when securing the clamp.

If the recoil assembly becomes inoperable, remove the recoil starter to expose the manual start pulley. Next, it is important to rotate the fan shield and replace the 3 bolts to hold the fan shield and fan cowl in place.

Restore pump site to the way you found it. Collect and remove garbage and litter before leaving the site.
