SOURCE: McCulloch 3200 takes many pulls to start, runs good when does.
I don't think I can help, but normal starting procedure for me is to put choke on, pull on recoil until it kicks over once. shut off choke and restart. Sounds like you have fixed almost everything & adjusted mag right. Rick

That is where I would go. Maybe carb clean or kit if it is a sudden change.

CW is leaner; to lean will destroy the saw. If over tightened closed (CW) the adjustment screw faces are easily marred; marred adjustments are difficult to impossible to set properly.
Clean the air filter; adjusting with a dirty filter can cause a run lean condition once cleaned and the saw run.
There are 2 wav (sound - idle & full – may not be highlighted) files that I find most helpful, I think you will too.

The best thing you can do to these engines it take them completely apart - take piston out and everything. Believe it or not, my 12-year-old son was able to do it - very few parts in these little 2-stroke engines. He polished the carbon off of the piston with a drummel tool and cleaned everything with carb-cleaner. Put it back together and it ran like a champ. Still does. It was a great learning experience for him too. The worst that can happen is you have a bunch of parts that you will throw away.

Check the fuel filter and muffler for plugging. Check the fuel lines for condition. Check the carburetor fasteners for tightness. If the saw has a lot of hours, remove the lower section of the carburetor and check the condition of the diaphragm--it should not be hard/cracked. If everything seems to check out ok, Turn both jet screws CW to stops (lightly), then CCW each 1-1/2 turns. The engine should start and run--allow the engine to warm up. Pull the throttle full on and adjust H needle CW til the engine speeds up, but still 4-strokes. Proper adjustment is when the engine 4-strokes, but immediately 2-strokes when cutting. Let idle and adjust L CW so that the engine runs fairly well, but allows the engine to 'follow the throttle'. Adjust the idle speed screw so that the chain stops turning, but the engine continues to run. Hope this helps!

Its either sucking air in throgh a loose connection in the fuel line or the carb is stopped up. Take it apart very easy so you don't rip any gaskets, and clean evertthing with a can of compressed air blow all the tubes out real good. You may have to get a carb kit it that does not work.
But that sounds like what it is, running out of gas when you let more air to it.

Please read this... Dolfoff carburetor threadhttp://www.fixya.com/support/t3026775-sa...
Excellant start procedure. It isn't spark. I think you have a leaking fuel line, dirty fuel filter, or most likely a little dirt in the carburetor. It is beyond my level of expertise to tell how to clean the carb, soneone else will be along soon.
