MS270

[TnShooter]

Can anyone tell me the main differences between the MS270 and the MS271 ?
I have a MS270 with a 20” bar. It was my step father’s. He gave it to me recently.
I remember him having the shop put a 20” bar on it when he bought it.
It has a FarmBoss bar on it now.

I can’t find any info on the 270. Only finding info on the 271.
Will the 270 run a 20” bar with little issues, or is the 20” too larger?
Are the Oilers the same on the 270 and 271?

Thanks everyone.

Can’t answer all your questions but found a link to the Stihl website for the manual and it lists 16-20” bar setup.

No, 2 different saws altogether. Here are the manuals.

The MS 270 is the newer improved version with a stratified scavening engine, compared to the MS 270 with a traditional 2 stroke engine. Also the air filter has a pre-seperator for substantially longer air filter service life. Engine data is not that much different.
Displacement MS 270: 3.0cu in (49.6cm³), 2.6kW
Displacement MS 271: 3.06cu in. (50.2cm³), 2.6kW

Oil pumps are not the same between the MS 270 and 271. Max Output on the MS 270 is around 10cm³ per minute and, around 8cm³ per minute on the MS 271.
