I have a CS-352. Pulled the limiter caps, got the carb a bit richer, about 1/2 turn on the H. So now its not going to burn up. Happy with the saw. I have watched a bunch of you-tube videos about muffler mods. One guy just dremeled out the exhaust guide, another "stabbed" the matrix from the rear to gut out the internals, and another bent open the seams and gutted the can that way. I raced 2 stroke dirt bikes from the mid 70s till just a few years ago. I know 2 strokes. These saws dont technically have expansion chambers, so I think the idea of the muffler mod is to reduce back pressure. But I know you dont want to eliminate back px completely. I just got ordered a used muff off ebay ($19) and thats going to be my guinea pig.
So my question is what are most people doing to the muffler to wake this saw up? I would think you would want to match the muff opening to the exhaust port. And open up the exhaust guide plate some? My stock muff has internal baffling, but I think the ebay muff has matrix internals that came with earlier serial numbers on this Model
Any help would be appreciated. Here is the ebay muff
