Installation Instructions
- Prepare the Engine: Ensure the engine is off and cool. Disconnect the spark plug wire for safety.
- Remove Old Starter (if applicable): Carefully unbolt and remove the existing pull start starter from the engine casing. Note the orientation and any spacers.
- Position New Starter: Align the KING PS-49B-10 starter with the mounting holes on the engine. Ensure the starter pawls are correctly positioned to engage with the flywheel cup.
- Secure the Starter: Insert the appropriate mounting bolts (not included) through the starter's mounting holes and into the engine block. Tighten the bolts securely, but do not overtighten, to avoid cracking the housing.
- Verify Engagement: Gently pull the starter rope a few times to ensure the pawls engage and disengage smoothly with the flywheel cup. The rope should retract fully.
- Reconnect Spark Plug: Once installation is complete and verified, reconnect the spark plug wire.
Operating Instructions
- Engine Preparation: Ensure the engine is properly fueled and oiled according to the engine manufacturer's specifications. Set the choke and throttle as required for starting.
- Pulling the Rope: Grip the pull handle firmly. Pull the rope slowly until you feel resistance (this indicates the pawls have engaged the flywheel).
- Starting the Engine: Once resistance is felt, pull the rope with a quick, strong, and smooth motion. Do not pull the rope to its absolute maximum extension.
- Rope Retraction: Allow the rope to retract slowly and completely into the starter housing. Do not release the handle abruptly, as this can damage the recoil mechanism.
- Repeat if Necessary: If the engine does not start, repeat the pulling process. Avoid excessive pulling without allowing the starter to cool down if it becomes hot.
Maintenance
- Cleaning: Keep the starter housing clean and free of dirt, debris, and oil. Use a damp cloth to wipe the exterior.
- Rope Inspection: Periodically inspect the pull rope for fraying or damage. Replace the rope if any wear is observed.
- Recoil Mechanism: The internal recoil mechanism is generally maintenance-free. Do not attempt to disassemble the starter unless you are experienced with such repairs, as the recoil spring can be under tension.
- Mounting Bolts: Check the mounting bolts periodically to ensure they remain tight.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Rope does not retract fully. | Damaged recoil spring or rope guide. | Inspect for obstructions. If spring is damaged, replacement of the starter assembly may be necessary. |
| Starter pawls do not engage flywheel. | Worn pawls or incorrect installation. | Check alignment and ensure pawls are not worn. Replace starter if pawls are damaged. |
| Rope is frayed or broken. | Normal wear and tear or improper pulling technique. | Replace the pull rope. Ensure smooth pulling motion. |
| Engine does not start after multiple pulls. | This issue is likely related to the engine itself, not the starter. | Check engine fuel, spark plug, carburetor, and compression. Consult your engine's manual. |
