Frequently Asked Questions

What chain does a Stihl MS271 or MS291 take?

Most MS271 and MS291 saws run .325" pitch × .063" (1.6mm) chain. Some versions use .325" × .050" (1.3mm). Common drive links: 16" ≈ 67 DL, 18" ≈ 74 DL, 20" ≈ 80–81 DL. Always check the stamp on the motor end of your bar.

Will Sugihara, Oregon, or Tsumura bars fit my MS271/MS291?

Yes. Any bar made for Stihl Group 3B (3003 mount) with matching pitch and gauge will fit. Solid-billet bars from Sugihara and Tsumura are popular upgrades for stiffness and durability.

What is the best bar length for an MS271 or MS291?

The 16" (≈67 DL) and 18" (≈74 DL) are the most common and best balanced lengths for these saws. A 20" bar is usable for extra reach on the MS291 but is near the practical limit for the MS271.

Do I need a new sprocket?

Only if the current one is worn (deep grooves) or you are changing pitch. Standard .325" setups use the original sprocket.
