Why is my lawn mower smoking????

I have a craftsman lawnwower model #917.376536. The last two times, i have used it, it has been hard to start and when it does start, heavy white smoke comes out and stays. it is only a year old and used only about 10 times. I am not mechanically savvy-so use simple words and easy directions.

Thank you for your question.

I am sorry you are having a problem with the mower. White smoke means the engine is burning oil. I recommend checking the oil level first. If it is over filled that is the problem. Adjust the level down to the full level. Then remove and inspect the air filter. If the filter is oil soaked, it should be replaced. Before installing the air filter start the engine but do not mow with it. It is going to smoke for a while until the oil is burnt out of the muffler. After the smoke stops wipe the engine with a paper towel and install the filter. Now you can use the mower normally.

The instructions for draining the oil and replacing the air filter are posted below.

Please let me know if you need further assistance.

Thank you for using Manage my life.
