When the engine on your backpack sprayer is not starting, the first parts to check is the recoil starter and the flywheel. Common issues with a recoil starter could be a broken string or a jammed string. If this is the case, replacing it will be your best option.
Our crew at the warehouse demonstrated step-by-step how to replace both parts on a backpack sprayer.
Tools You Will Need:
- 8mm Allen wrench
- 14mm socket wrench
1. Use a 8mm Allen wrench to unscrew the old recoil starter from the plastic housing of the engine. There will be 5 screws holding it in place.
2. Remove the old recoil starter from the plastic housing on the engine.
3. Replace with a new recoil starter by screwing it onto the plastic housing.
Is your recoil starter working fine? Check the flywheel next.
Here's how to replace the flywheel on your backpack sprayer:
4. Insert a screwdriver into the fan in the engine's plastic housing to stop it from spinning.
5. Use a 14mm socket wrench to loosen the old flywheel from the engine housing. 6. Screw on the new flywheel by hand or with a 14 mm socket wrench.
7. Reattach the recoil starter onto the plastic housing.
