MS 460 Magnum, Max Flow Air Filter, Bark Box, duel port muffler mod, . 74 main jet, Carburetor tune 

I’ve had several of these saws, still kinda have one left. It’s a new XS440 hybrid. I did a bit of jet testing on this saw and never really saw any difference maybe a tad more grunt but the saw was built for torque to pull longer bars

Pięknie pracuje 💪👍🙂

Walbro brand direct replacement jet. Did not do any timing Advance as it did not have any porting done to the cylinder. I will be uploading a new video with the .76 jet soon. My other video shows exactly what I do to the saw on the bench. The title of the video is about the difference between the 460 saws.

Did you ream the jet yourself or buy one aftermarket. Did you advance the timing?
