drain all the old fuel as the oil will have degraded and will seize the engine if used, personally I would use a little more two stroke in the fuel and make sure the air filter has been cleaned before starting. Make sure you dont rev the motor heavily until the new fuel has come through the carb. Check the chain tightness and ensure it runs freely, make sure the chain brake works and the chain catcher is in place - fill up with fresh bar oil.
Good luck
