On November 10 last year I showed you a few photos of a Stihl MS661 I’d picked up in very rough shape. Check it out on my Facebook page. ProSaw Services.
After a lot of parts ordering & waiting she’s buttoned up.
This one was rebuilt from the crankshaft up with 100% OEM Stihl parts. The 661 is not a weekend warrior saw, or an occasional firewood cutter. It’s the number one selling pro saw in the world for a reason, and deserves the best parts.
The timber workers that typically opt for a 661 want absolute reliability. Down time is lost time.
It’s now wearing all new gaskets, bearings, seals, piston kit, cylinder and front handle. It’s also been upgraded to 3rd gen Mtronic with a new coil/ecu and fuel solenoid.
