Questions people ask

What size chain does a Stihl MS291C take?

The Stihl MS291C chain depends on the bar. 16" bar: 3/8", .050", 60 drive links; 18" bar: .325", .063", 74 drive links.

How many drive links is a Stihl MS291C chain?

It depends on the bar: 60 on a 16" bar, 74 on a 18" bar. The bar length is usually printed near the mount.

Can I use a chain with the same length but different pitch?

No. Pitch and gauge have to match the bar and sprocket, and the drive link count has to match the bar. A chain that is off on any of the three will not fit or run safely.
