0 My 610 saw has a 'ZAMA'carb fitted. I've recently fitted a rebuild kit. Not sure exactly what settings you are referring to, but assume you mean the LOW & HI needles visable from the pull start side of the saw. A start setting for both is about 3/4...1 turn open from the closed position. both are then adjusted as required depending on how worn the carb is. The third rear most screw is the idle speed adjustment which one would start off with screwed 2..3 turns to get saw going, then as the idle screw is fined tuned so the idle speed is reduced to a smoothe idle.Then the HI needle is tuned to loaed revs. Depending on your skills, it is important to ensure that the chain brake is operative, better still remove the chain and bar from the saw completly, so no chance of being injured then. If the reason for your question on settings is to do with the saw not running /starting, its fair to point out that if the saw has been running some time ago, its not relistic to think that the settings have changed markedly by them selves!......so you may need to look in other directions. Lets know how you get on. good luck
