Kind of a side note, what flange did u use to pres/vac test? Is it a stihl part?
WANT ME TO BRING A CARB OR 5?

What have you tried on the H and L screws? Limiter cap still on the H? I rebuilt a 362 last week (the one above with the broken piston) and the L screw was off just enough that it wouldn't start and advance throttle when I put a new piston and cylinder on it.
The two symptoms that will follow carbs and create dieing while idling and poor acceleration are the tank vent and the fuel line leaking. I have had fuel lines leaking around the inlet nipple on the carb that cause the problems you are having. The lines will look o.k. and even pass a pressure check from the carb end because the nipple on the pressure pump is bigger than the carb nipple. I always check fuel lines from the filter end while the other end is still installed on the carb.
Just tossing around ideas. I feel your pain...I've been there.
If using a Stihl plug for the two intake channels, it automatically also tests the impulse line, that also checks the intake boot. I test the fuel tank by pressurizing the tank through the fuel line from the carb end. It should hold pressure. With vacuum applied it should not hold vacuum.Man what a PITA.
Did you vac check the fuel tank from the fuel line? Check the impulse line for leaks when you pressure and vacuum tested the engine? Check gaskets and intake manifold? Double check compression with a different tester as the compression was slightly low. Good OEM fuel filter? Fresh fuel mix? Were the carbs you installed known good ones?

Low compression would do it for sure, but those are funny symptoms. If it still acts up after installing the new rings, the fuel line may be collapsed internally.
Hey man, I appreciate you checking in regardless! I've had too many false hopes with this saw, but at least with this bit of cash & waiting time I can take comfort in knowing it was needed and not just some shot in the dark.Every time I think of something to check, the next post is you trying it and I not working.
Sorry no help, just sympathy!
Did you check the intake boot?
