FAQs
Will this choke knob fit my non-Rocwood chainsaw?
This knob is designed for Rocwood SL5200/SL5500 and many other Chinese 51/54cc chainsaws (like 4500/5200 series, Taurus, Timbertech). It's essential to visually compare it with your current choke mechanism or check your chainsaw's manual for compatibility before purchasing.
How do I know if I need to replace my choke knob?
You likely need a replacement if the knob is broken, difficult to move, doesn't properly engage the choke, or if the linkage is visibly damaged, leading to starting issues.
Is installation difficult?
Installation is generally straightforward, involving removing the old knob and attaching the new one to the choke rod. Basic mechanical aptitude is helpful, but it typically does not require specialized tools.
What is the main function of the choke knob?
The choke knob controls the choke plate, which restricts airflow to the engine. This is crucial for creating a rich fuel-air mixture needed to start a cold engine.
Does this part come with the choke rod?
No, this is the choke knob lever itself. It is designed to attach to your existing choke rod. You will need to reuse your current rod.
Can I use this on a 45cc Chinese chainsaw?
Yes, it is listed as compatible with 51cc/54cc engines, which often share similar choke mechanisms with 45cc models from the same manufacturers. However, visual confirmation with your existing part is always recommended.
Troubleshooting
Choke knob is stiff or difficult to move
Ensure the choke rod is clean and free of debris. Apply a small amount of light lubricant to the rod and pivot point. Check for any obstructions in the linkage.
Choke knob does not engage the choke plate
Verify the knob is correctly attached to the choke rod. The rod itself might be bent or disconnected from the choke plate inside the carburetor; this requires further inspection of the carburetor assembly.
Choke knob is loose or wobbly
Check the fastening mechanism (screw, clip) that attaches the knob to the choke rod. Tighten or re-secure as necessary. If the rod's attachment point is damaged, the rod may need replacement.

Setup, Compatibility & Care
Setup:
- Ensure the chainsaw engine is off and cool.

- Carefully remove the old choke knob, noting how it attaches to the choke rod.
- Align the new Rocwood Choke Knob with the choke rod and secure it according to the original mechanism (usually a screw or clip).
- Test the choke lever's movement to ensure it operates smoothly and engages/disengages the choke plate.
Compatibility:
- Primary Fit: Rocwood SL5200, Rocwood SL5500.

- Other Brands: Taurus, Timbertech.
- Verification: Always compare the part number (75307) and visually inspect your existing choke mechanism to confirm it matches the design before purchase, especially for non-Rocwood branded equipment.
Care:
- Keep the choke knob and its linkage clean from dirt and debris.
- Periodically check that the knob moves freely and is securely attached.
- Lubricate the linkage slightly if it becomes stiff, using a light-grade oil.
