Thread: 020T Muffler

Is it bad for the chainsaw to run it without a muffler? I was taking a tree down and the muffler came loose second time it happened It is alittle loud. Maybe it'll wake the neighbors up and I can get more work.

I have a customer who runs his 025 with no muffler. It works for him but I would not do it. The muffler acts as a filter of sorts to keep debris out of the cylinder. Also keeps the saw from setting the woods on fire. I had a Maico dirtbike that scored a piston from an exhaust leak. Open exhaust can't be good.

I know some here will complain that many mufflers are too restrictive but the thing is a 2 cycle needs some backpressure from a properly functioning exhaust system to produce maximum power.

Also as already stated a lose or missing muffler allows dirt entry and when shut off, cold air directly on the piston and rings, warpage can ocurr.

Open it up a little while it's off and then put it back on.

A neighbor ruined his saw after the muffler fell off and continued cutting. How can you stand the noise?
