Unless you remove the limiters from the needles you will not be able to adjust the carb by putting the needles into the seats and turning 1 or 1.5 out. If the saw will run, turn the LA or T or idle screw in far enough to get the chain moving on the bar. Then turn the L needle in or out till the chain is moving as fast as possible on the bar. Blip the throttle a few times to make sure. Now turn the L needle about ¼ turn counter clockwise (pinch rich) and turn the LA screw counterclockwise till the chain stops moving on the bar. This should set the low end of the saw. The saw should accelerate normally. To set the H or high speed, you will need a tach. If the above adjustments don’t work, you will need to rebuild the carb or the saw has deeper problems. Best to do this with the saw clamped in a bench vice.
