Are you looking for the ultimate lightweight rear handle climbing saw, or just a ripping little firewood saw?!  309 Machine’s CNC ported HP261 packs a lot of punch in a little package. 

HP stands for High Performance, and that's what we are all about. We strive to maximize power while focusing on durability and reliability.

309 Machine offers the only 3/4 Wrap version of the 261.

Port work includes:

  • CNC Cylinder porting
    • Exhaust Port enlargement, timing and polishing
    • Intake Port timing
    • Squish band cut for smaller combustion area
    • Base cut for increased compression
  • Removal of decompression release
  • Muffler modification and install of WCS Port

309 Machine recommends the install of a WCS filter to allow maximum performance. 

Consider converting to 3/8” with the 3/8”-7 Sprocket.

Any accessories ordered with the saw will be installed and shipped with the saw. 

Saws will ship with a 20” Light 04 bar in .325” and a 23RM3 chain.

This saw is absolutely amazing and the custom full wrap handle bar is a piece of art. I run this saw 4 to 5 days a week and I enjoy everytime.

Mike absolutely knocked it out of the park on my 261C! Just ran it today, for the first time, and I'm very impressed with this saw. Also, love that he installs everything you buy for it, including the 3/4 wrap that he makes(a must buy in my opinion). Definitely recommend 309 to anyone looking for that extra performance in their saw🤙🏻

STIHL MS261 ported.

Very responsive and runs strong. Love the details of engraving 309 on the head and decompression elimination bolt. Thanks again for your fast shipping and looking forward to getting my 500i back from 309 for porting also.

This is a great running saw. I have a 3/8" chain on a 20" bar. It runs sharp and clean, revs very quickly and sounds great with the WCS port. I only have one tank of fuel through it. I look forward to many more. Customer service and shipping are second to none.
