Nice set of saws. It can be hard to locate mufflers sometimes, certainly if the "correct" muffler is desired. I am not usually that picky. The largest bore that I have come across for those was a Mahle 57mm, supposedly factory for the 910s. Put the 910 at 95cc, I asked a couple of the local folks and posted a thread here but did not get any other information. The stand out comment from one of the locals was sometimes a fellow could get his hands on a real runner.
Other than the one 57mm P/C the rest have been the 54mm 9xxs. One of the reps mentioned on the 930s that there was supposedly a run of 56mm P/C but I have not seen any of those.
I really enjoy the 2094/95s but do not use them much anymore since sourcing local parts is pretty much over.
Also wanted to elaborate a little on the mufflers reputation, it was not uncommon for them to burn through, especially at the corners or around the openings. I pretty much just expect to need to find a muffler if I was purchasing a used loggers saw. The 2094/95 mufflers were well known for dropping the deflector and burning through the chain brakes, so add a brake flag to costs of restoring a logger's saw. If they were harshly dented then they would typically burn through the dent creases. I have brazed and mig welded lots of those mufflers just so I did not have to beat on a new one. The other mufflers in the 900 series have been a rare local find for a good long while.
Those saws were quite popular locally after the 920s came out, the 910s sold well enough by the one dealers account but things took off with the 920/930s.
