Mail us your old powerhead and we'll take care of the rest! Let 309 Machine wake up your saw with CNC Porting. We specialize in increasing power while focusing on reliability and durability.

Most saws include:

  • CNC Cylinder porting
    • Exhaust Port enlargement, timing and polishing
    • Intake Port enlargement, timing and texturing
    • Squish band cut for smaller combustion area
    • Base cut for increased compression
  • Muffler Baffle modification & port matching
  • Decompression removal and plug installation

Some saws include:

  • Carb Tuning after porting
  • Timing advance

261C-M or 261 Port work includes the parts and installation of a WCS universal port onto the muffler.

201TC-M Port work includes the parts and installation of a WCS 201 muffler. If you have already installed an aftermarket muffler, use discount code muffler to remove the cost of the WCS muffler. All saws must have either a customer supplied muffler or will need a WCS muffler installed when port work is performed. 

If the saw is received in an non working or unrepairable state or is deemed unfit for port work, the saw will be returned to the customer and the order will be refunded minus shipping and a $200 fee. We will not work on any saw that has already been ported on.

309 - 500i, 261, 201

We bought two saws from Mike and had one of our 500i's ported. All the saws are top notch, saws showed up nicely packed, and he gets them done lightning fast. Don't worry about being down a saw for long, you'll get it back quick. We use these saws every day for tree work, the 500i absolutely slays, tons of top end, no bogg down. One thing that really stands out for me is that you can call Mike with questions and he'll give you his best answer. Even if he doesn't pick the phone up on the first shot he calls back. Pretty awesome to be able to talk to the man that's working on your saws. We will be sending him more saws to port in the future. 309 Machine is the real deal.

Awesome Saws!

May 12, 025 I ordered the HP 261c online.and had it delivered at my house in Pennsylvania on May 15 2025! I was cutting a big locust that afternoon. I decided to call 309 Machine to thank them. After speaking with Mike I decided to send him my 500i, which by the way total turn around time was 4 days for Mike to work on my saw dye the plastic and get it shipped back to me. His work ethic and attention to detail is second to none! His quality of work is excellent, both saws are awesome! I would highly recommend 309 Machine !
Thanks again Mike!

Ms 661 Done Right

309 machine is unbelievable!!! Had my saw back in 7 days -which is crazy awesome. Had the chance test it out a little on a huge pecan and not even pushing it this thing was FLYING through it like butter while the square chisel was still sharp! I could not be happier with the decision. Definitely worth it. Request list: Please let me know when you get the 201 online would love for you to work your magic on it too. Also if you make a bar spacer for the ms881 I would order today! Thank You!!!!

461 unleashed

WOW, Sent 461 stihl to let 309 work their magic, turn around was 1 week. I have worked it 2 solid days felling white oak in the midwest. I DON'T know what to say, thank you 309. I had no idea the stock version had so much left on the table. The torque, the chain speed, throttle response , AMAZING!!!! I LOVE IT! 309 MACHINE ROCKS!!!
