  If your MTD Lawn Mower engine cranks but doesn't start, several factors could be responsible. First, check that the throttle or choke is in the correct starting position, referring to the OPERATION section of this manual. Ensure that the gasoline tank is filled. A plugged fuel line or in-line fuel filter can also prevent starting; remove and clean the fuel line, and replace the fuel filter if necessary. Check that the spark plug lead is connected and test for spark. If no spark is present, have the engine’s magneto serviced by an authorized engine dealer.

  An MTD Lawn Mower engine may smoke due to several reasons. The engine oil might be overfilled, so check the oil level. The engine might be losing crankcase vacuum because the dipstick is not seated or is broken, in which case you should replace the defective part. Also, the engine breather might be defective and needs replacement.
