Thanks Brent. I actually messed up my Echo 490 earlier today. I went way overboard on a muffler mod by drilling a 1/2” hole in the center. It’s crazy loud now, but it has a nice sound to it. I’ll probably replace the muffler because now there’s no backpressure

Wont hurt it at all.
You probably helped it, necause now the muffler has become an "expansion chamber".
Kinda like the old McCullochs I tinker with. Just lets the "freedom" out. Dont worry about the noise. Better breathing is a good thing for a 2 stroke.

That was mean Dallas.
Especially the old ones with Sarah Mcglaughlin.

I'm ok. Got Tia spending the night with her aunt(wife's sister). Lucy is here, and we are having the "grand-dog" spend the night.

how is that mean ?
just showing her she could have it worse than she does

Wouldn’t it basically eliminate the backpressure because it’s a straight shot out the exhaust port? If that’s not the case, then I’m happy

what do you think the front dual port covers for the bigger stihls do ?
i have saws you can stick your fingers in the exhaust so 1/2 inch doesnt mean *s-word

Delicious!

They are pretty good considering they are gluten free crusts. Mom’s recipe, only the 3rd time in my life I have made them. I think if she was still with us she’d be proud.

Good to know. That would just mean the flow was increased and I just made a cheap dual port?

You’re watching too many YouTube saw hacks, like Tin pony. Back pressure doesn’t add anything.

next time dont put it on the front
it will reflect off the wood and right back at you

Oh.
You put the hole in the center of the shell.
Yeah.
See what Pat did.
That's more better.
You did pretty much the same thing, but the side exits do add some return for exhaust pulse. Hard to explain, but its all a timing thing.
It needs to breathe, but it also needs to equalize pressure in the chamber. No back pressure leads to negative chamber pressure on exhaust, which leads to inadequate charge on intake, which leads to bad things.

Ok. I see your reasoning.
As long as she does.

He’s the guy who does the $600 angle grinder port job. Takes the oem out and puts the chinese in. His port jobs lower compression and look like something I’d do with a crowbar while drunk
