Over on the SmokStak forum they said they are hard to get out, and if you try you should use vice grips on the mounting boss, otherwise you can rip it right out of the muffler sheet metal.
But the guy said once he got it out, hardly anything came out of the muffler anyway so it probably wasn't worth the effort.
Kroil is another good penetrating oil. I tried it on mine and gave up trying to get it out.

I had the same problem getting mine off. Soaked it in Kroil oil for several days and it would not budge. The screw came out but the spark arrester was rusted to the tail pipe. Finally I took a propane torch and got it hot then tapped the edge of the arrester with a hammer and screw driver around the circumference and it came off. I had about 350 Hrs on the genset and it was 12 years old at the time. There was not much carbon buildup on the inside screen. I imagine if the genset is running rich, carbon can build up quicker.
