A couple things I'd look at. Just my guess that the grass id a bit damp considering how nice the weather has been lately. See if you have a bunch of build up under the deck. Next when I picked up my 2182 it ran decent or at least I thought it did, that a look at the spark plug I pulled out of it. So I put 3 new plugs in it, no change, new cap and rotor, no change, fuel and air filters, no change, new carb, yep no change. Pulled the plugs and found that one of the brand new plugs was NG. Now we are a happy camper. Maybe it's just me but the odd thing about the 3 cylinder eng is the tone doesn't seem to change much if it's only hitting on two holes.
If any of you 2182 owners need a good carb you know who has one
