Try turning in the idle adjustment screw a little at a time until you get the saw to idle but not move your chain.your manual or an online manual for your saw should show where the idle screw is located.

Most chainsaws I have used and fixed have three adjustments.
One adjusts the speed the saw will idle at, communally called an idle screw. You adjust this screw for the speed at idle.
Another screw will adjust the air.
One more will adjust the gas.
All saws may not have these last two screws, and may only have one for the air/fuel mixture.
I would suggest that you use the users manual then find the correct settings and where the screws are located.
The engine may not idle smoothly if the two adjustments which affect the air/gas mixture are not correctly set. This will depend on the way the gas/oil has been mixed as well.
If the engine will not idle correctly and the engine continues to run roughly or will not idle at all, then you may have to have the carburetor repaired. If the float is faulty, such as a hole, dirty, or the float shutoff pin is sticking, then repair needs to be done.
You can usually find repair kits for these at repair shops which carry parts for these saws and other small engines as well.
Another thing which is common is water in the gas causing rough idle or the engine not running at all.
Water can get in gas from cans sitting or the saw in an area which can have rain or temperature changes which can cause water from humidity build-up in the tank.
