Take a very small and sharp chisel and whack the head of it counter clockwise until it moves. Alternate this with your other method.
Stuck muffler bolt! I need better torx bits... Two down so far.

Surprised no one suggested heat, steel doesn't expand as much as aluminum. I would carefully heat that mule and give it a spin
If you can reach it with a dremel cutting disc, cut a slot so a standard scrench will fit??
Nothing worse than 1 bolt removal taking 5 times the time of the whole job

What about going back and forth? There might be just a little tight loose play.

Soak for a few days by periodically applying 50/50 mix of atf/acetone.
Heat and use a manual impact. Start lightly, one hit loose, then tight. Back and forth a few times. Then give her hell backing the screw out. The manual always works better than powered because it applies a downward strike that helps break the rust.

Heat gun and some form of penetrating oil. WD-40 will work. If you don't have a heat gun then run the motor and try removing it while its still hot.

I have a heat gun and a propane torch. But I will have to tear the whole unit down because it is between the fuel tank and crankcase. I have access to it but anything over a wide area will melt plastic.
And why the hell is it ALWAYS the last one?

Well, I got the bolt loose. I switched to a battery with more charge. I kept going back and forth. It gave on about four or fifth switch. I guess leaving it sitting with PB blaster on it helped.
It was the last one! How did you know?!?
I pulled the muffler and it was a little restrictive, I guess because of noise. I don't have a screw driver that fits the needles. There are two but before I grind out the muffler, I want to make sure that the needles do change the tune. I expect them to but I want to be sure. I can't do too much, this engine is rev limited. The NEEDS tuned cause it is too slow/ too rich and kinda rough. We can fix that!

Well, it went back in just fine but I will replace it. It is just about hand tight now.
I am going to have to order the Wiha bits, which ever I choose, just to finish this project!

Trying them all
If you open up the muffler, that may lean it up a bit. I haven't found a muff mod to make too much of a difference in tune on most saws. Usually needs about 1/16 to 1/8 of a turn richer on the H screw.

Well its 's not a saw. It is a backpack blower... Sorry!
But it needs opened. The exhauat port on the muffler is about a third of the exhaust port on the cylinder. I can't think of any reason for that. Outlet to the deflector is tiny. I don't think I will get more power, just a better running engine.
