Been messing with transfer ports on a couple spare jugs. Most recent change pulls hard but lost rpm. Thinking the blow down is too low at rpm now.

Thanks for the in depth report about the muffler mod, I think the best way to get more power without risking reliability is buy a bigger saw

The 550 I ran with muffler mod didnt seem to cut any better then my stock one. Just the muffler modded one was LOUD as all get out. To loud IMO.

 Would be interested to get the one back from my buddy I rebuilt and muffler modded and see where it is since I reset it. Not sure how he did his mm but I cut mine in half and removed the baffle or cage completely. My buddy that owns the saw says the mm pulls harder than the stock version.

A/T should compensate for the less restrictive muffler.  Played around with many different stinger lengths on my 562 muffler from a comical 11" down to just under 3"

Try this out sometime, changes in length are noticeable in different power ranges
