McCulloch Help

[DirtyDan]

Hello! I posted about this saw a while back and have been slow working on it. I am hoping this will be the last hurdle (for now).

I took the saw apart, cleaned the carburetor, put in new gaskets, new fuel lines, bar and chain oil line, cleaned the air filter, filter on the fuel line, and oil line filter, and fixed things that the previous owner "fixed."

I am now here. It starts (thankfully) but refuses to idle. I am unfamiliar with the high, low, and idle screws. When I had the saw apart, I tighted them down all the way, then backed them out one turn each to serve as a "baseline." Are these screws and their adjustments the remedy for this issue given the repairs I have done?

Thank you all for your time and expertise!

It looks and sounds like the chainbrake is engaged in your video, you want to pull back / toward you on the chain brake "flag" so that the clutch drum can spin freely and the saw can rev up a little.
Assuming the carb diaphragms and gaskets are assembled correctly, and the metering lever and inlet needle are correct, I'd try turning up the idle adjustment screw clockwise to see if it will idle and maybe give it a quarter turn counter clockwise on the low speed adjustment to give it some more fuel at idle and see if that helps at all.

Good call. The brake was engaged (slipped my mind). Gaskets and diaphragms were carefully assembled as well.
Thank you for the tips regarding the adjustment screws. I will definitely give that a shot tomorrow!
Thank you.
