New Echo CS-355T

Thanks. I'm a tig welder and I can make something like that fairly quick from scrap that I have lying around.
I would guess that you need to open up the carb a LOT for that...particularly at sea level.
Rochester 650cfm double pumper...

Gotta love a 3" blue flame out of a tree saw with chips flyin out like it's a snowblower

Is that your saw? If so, do you know the inside diameter of the pipe?

Yes, I'll get you specs. Imo, they used a heavier guage than needed.

SWW -- Did you by any chance get that inside diameter?

Don't go to any trouble to get it ... since I can probably just make the inside area of the pipe 85% of the port opening area and then choke it down from there with a screen if need be (I think 85% was the rule of thumb)...

Thank you sir. I see what you mean about it being heavier than needed... I appreciate you taking the time & trouble.

Stainless would be lighter as well.
