Got this weird problem with my Craftsman/Poulan 2.0 saw. While using it one day the saw just shutoff, and would not restart at all. Also while opening the throttle all the way while pulling the things makes whistling sound now. Got it running again but now the carb was way off and had to adjust a million times until it was right or at least I thought so. Next time I tried to start, nada, had to use either and she started, ran like crap and adjusted a millon times again. Changed fuel line, rebuilt carb, and flipped reed valve??, no change, and still whistling on cranking???? Could it be I need a new reed valve?? The saw will cut fine and run good but the adjustment never seems right all time. Also while reving it you can see heavy fuel droplets, and some shoots back out the carb??? Anyone got any clues?? The reed valve dosn't look like it closes too good.
