Remember that if the springs in the clutch are broken the clutch will not disengage and the chain will always turn
If the chain turns on the bar when the saw is at idle, then the idling speed is still too fast. If you turn the idle screw down until the chain stops moving, it should still idle well enough not to stall. The chain should not move at idle.
If you turn the idle screw down until the chain stops and it won't idle, then you have to adjust the low speed carb screw. Odds are if you back off the idling speed until the chain stops moving you'll be fine. The idle screw is usually the one with a spring under it to maintain torsion. Somes the throttle plate, the one with the throttle wire against it, will rest against a screw stop for idle control. This is the easiest adjustment. Just back it out until the plate returns more and the speed will drop.
Make sure it is lubricated and not clogged up with sawdust.

If lowering idle speed does not stop chain broken clutch springs will cause chain to not stop

Thanks for the info. I will give it a try. The saw is actually an echo cs-3400 type 1E with a 16 inch bar. If this makes a difference please advise. Thanks again
