Been searching the muffler mod posts and decided to have at it on a new Mac 1838 I just picked up for $52 on Ebay instead of the higher end saws I own. The saw was a big dissapointment for power, it was so pittifull you had to hold up on the saw on a 10" cut. The carb couldn't be adjusted right either. Lean enough to have some RPMs and no torque. Open it till you had some torque and no RPMs. Drilled three 5/16" holes in the baffle, pitched the spark arrester and opened the exit up where the big restriction was. It had just a few approx 3/16" holes there. The only thing I had on hand by the shop was a couple maple knots that resisted the splitter and that saw runs like crazy now, actualy could lay into it a bit. Funny thing is that it now responds to carb adjustments very nicely too. I have it just rich enough that it "bubbers" (I dont know what the proper term is) at the end of a cut. I did have to rid it of the adjustment limiters to get it rich enough after the mods. I know it still is a throwaway and aint no race saw but it is fun to run now, yesterday when working a fence row before the mods my youngest was going to throw it in the creek, now he wants the MS210 muffler to go under the knife too, LOL.
