It sounds like it could be the carburetor.   Try adjusting the L side out by half a turn and then see if there is any improvement.   The H is for wide open throttle and the L is for idle and transition to WOP.   If you get it to rev then make sure you adjust the H for the 4 stroking sound at WOP throttle and then when you put it in wood it will smooth out to 2 stroking.   

If the carb adjustments have no effect then you must have an air leak in it somewhere and you need to start checking things.

Well not all carbs have both adjustments.  Most of them do but sounds like yours does not.     The main thing is that your saw sounds like it has a lean condition not enough fuel.   It is either the carburetor or it is a air leak causing it to be lean.

On you carb the adjustment that is closet to the intake is the low the one closet to the air filter would be where the Hi would be.   If there is a adjustment there for the L I would still turn it out ccw by half a turn and see if the saw runs any better.
