Stihl MS 261 C-M vs Stihl MS 311
Tinted cells mark the better figure on that row alone: more engine, longer bar, lighter, cheaper. A lighter weight is only a win on the same basis.
What owners like and complain about
Stihl MS 261 C-M
- 3.0 kW from 50.2cc at 10.9 lb — the best power-to-weight in Stihl's 50cc class and 1.4 lb lighter than the MS 271
- Magnesium crankcase and pro chassis: designed for rebuilds, with full parts support
- M-Tronic removes carburetor screws and re-trims itself for altitude, fuel and filter condition
- Runs 16" through 20" bars on .325"/.063" without the oiler falling behind
- Owners who run several M-Tronic Stihls report no resets at all on non-ethanol fuel
- M-Tronic faults are a dealer-laptop job — owners report brand-new saws that would not idle
- $760 is roughly $230 over an MS 271 Farm Boss of the same displacement
- Reported engine failures inside four years with roughly $400 parts plus $100 labour to put right
- 2026 warranty is 1 year consumer and only 3 months if you earn money with it — short for the price
- Dealer-only sales, so there is no discounting it
Stihl MS 311
- 3/8" .050" chain and bumper spikes — proper felling and bucking gearing, not homeowner narrow-kerf
- Pre-separation air filtration stretches filter intervals noticeably in dry, dirty cutting
- IntelliCarb compensates as the air filter loads, so mixture does not drift rich during a long day
- Owners report high firewood output with a 16" bar and a well-filed full-chisel chain
- Side-access tensioner and toolless caps make bar swaps quick
- Same 13.8 lb powerhead as the MS 391 for less power at the same list price — hard to justify at full retail
- Bogs in hardwood with a 20" bar; 16-18" is where it actually works
- Owners repeatedly call the power-to-weight poor and the saw plastic-heavy for the money
- No M-Tronic at $760 — you still tune the carburetor for altitude and season
