Fortunately, for the sake of this photo account of the muffler saga, I had installed the muffler on a temporary basis, so I could make sure that the saw would run, knowing I'd need to reinstall it using Locktite at a later time.
The muffler body fit the cylinder perfectly, and the baffle and cover mated up just as nicely. The only hitch was that the three shouldered screws that hold the cover on did not match the threads of the new body, for reasons I can't explain. A trip to the local hardware store helped me determine that the new body had nuts with 10/32 thread, but I never could determine for sure what the threads were on the screws that fit the nuts in the old body. They are finer than 24 tpi but coarser than 32 tpi. Maybe 10/28?? Anyway, as you can see, I built my own stainless shouldered screws using paired nuts with a lock washer in between. Kinda unique! Next week my new (to me) 32 inch guide bar should arrive. I'm anxious to try it out on a huge oak that stands in our house-yard that is in the way of an addition for which we are breaking ground this spring. It's a beautiful tree that I hate to lose, but it's standing in the way of progress.
My 1971 XL 923 with her running mates, a 1991 Super XL and a 1968 XL 12.
And, yes, I also have a plan to fix the missing spark plug shield on the 923. More photos to come. Thanks for your interest in my project. O.
