I noticed the other day that my muffler was a little loose so I decided it was a good opportunity to try a muffler mod. I bought this saw brand new in 2000 and I changed the spark plug once and cleaned the air filter, maybe twice.... Never thought much about it, it always ran great! I've cut probably upwards of 100 or so cord since then for firewood. It was my only saw until recently... Then I got CAD... But I digress.
So I pulled the muffler and checked the piston, looks great!! Saw could use a good cleaning though.
The muffler looked like this.

So I pried the baffle out a bit with a screwdriver.
Then I grabbed it with a pair of pliers and twisted until it broke free.
.
Then I spread the outlet baffle a bit to give it a bit more room.
The spark screen slid right back where it belongs. Not sure if it would be better to eliminate it. Any thoughts??
My spark plug looked like this.
Does it look good or a little lean???
Compression was about 163 cold.
I put it back together and fired it up.
I had to richen up the low setting a little for it to idle good.
Then I did a few cuts. It sounded to me like it was 4 stroking out of the wood and smoothing out in the cut with no adjustment to the high???
I took a video just not sure how to post it at the moment?
Any thoughts on why it didn't seem to need any adjustment on the high?
Maybe I had it to rich already? Plug didn't look it though???
