If you had to get it warm to get it up to 120 I would still say your motor is getting a little tired. I would be looking to stick a new top end up it here some time soon.

do the comp test cold......hold it wide open. kick til needle stops.  THEN record your #'s on each cylinder.  THEN take a teaspoon of 2 stroke oil you use....and put it down the spark plug hold and then repeat the test.  IF the compression is higher with the oil in there.......your rings are worn and allowing blow-by to cause issues with your compression.
