“New” MS261

[burnt03]

Gave up on fixing the 028 for now and the Jons630 was a bit heavy on the last load of wood so took the opportunity to treat myself to something “new”. Found a local 261 on FB marketplace, picked it up earlier today.

Came with a 20” .325 sprocket and bar but the guy had a 3/8 chain in it (at least I think so, wasn’t sitting tight on the nose… see pic). Changed it out with an 18” rollomatic bar and chain that I had on the 028 (3003 008 6617) and seems smooth now.

Question is - looking at a new chain for the bar on Baileys and it’s got a couple different semi chisel Woodland Pros: the 23SC74 and the 20SC74. Main diff in the specs is what chain it replaces…. But I have no idea what chain is on there now (it’s marked Stihl but can’t really see anything else).

Anyone know the difference?

The specs for the chain are stamped into the bar close to the power head.
Compare those to the specs for the baileys chain to see if they're the same.

Did the new power head look better than that old bar it came with?

Thinking along the same lines the 028 is a bit fussy to keep running.
Did you get the 261 set up correctly?
If so what's your take on going from an 028 to the 261?
