Watched it again paying more attention to the surrounding this time, looks like a workshop after all - my bad!

Shame, I thought it be kinda cool WOTing a chainsaw inside the house.

That's how I wake everybody up.
Basically a two stroke rooster.

You do any muffler mods on your rooster??
I usually drill a 1/2 hole in the rectangle area under the screen and two smaller holes on the outside cover to let more exhaust out.
I find opening the exhaust up on these saws really helps.

His pictures show a dual port muffler, one front and one on the side.

I'm guessing the one on the side is not stock.

Good eye Wilhelm...I missed the second port! Looks like Fruecrue has things covered!!!!
Sorry.....I'll go to my corner!! Lol

There are no corners on OPE, we all sit in a circle in a round room!

This saw also has Intake and exhaust ports widened, timing advance, and cross performance mesh air filter.
Rebuilt due to broken crank at flywheel nut.
Timed as follows;
Exhaust 102
Transfers 125
Intake 76
Squish .030"

Not bad for a clammy.
I'll try to get video soon.

Nice work Dall.
I did the same under the cover and port matched muffler inlet and gasket.

Cool stuff, I'm gonna rebuild my 290 with a 390 top end and do a muff mod.
