I just purchased a stihl ms 362, the first day , it bogged down litterally the chain stopped mid log, it sounds fine spooling and running but it just plain stalls under load. I took it to the shop the guy turned up the high idle, he said it should be fine now , saw the owner on the way out he said is everything ok i told i wouldnt know until i was cutting, that was tuesday, i never tried it until saturday (today) and same thing on the first cut ...no power... shops closed sunday and i will take it back anyone got any ideas to as what could be wrong , on this brand new saw
