Step 1

Check to see if there is any grass stuck between the blades if you are unable to pull the cord to start your Craftsman lawn mower's engine.

Step 2

Measure your tank's oil to make sure that there is enough in the engine if you are able to pull the cord but the engine will either not start, is hard to start, or will not stay started. If you have an electric starter, you will need to also check the battery. If the motor spins but doesn't engage the engine, the overrunning clutch or gear could be broken and you may need to get it professionally repaired.

Step 3

Prime the engine the correct way--improper priming is a common problem that can result in your engine starting easily but dying after a few seconds. Cold weather, for instance, requires your engine to be primed double of what it requires in warmer weather. Too much priming can flood your engine.

Step 4

Clean your Craftsman lawnmower's carburetor with a towel or rag if your engine is idling roughly or unevenly. If your carburetor appears clean, you may need to contact a technician to check for air leaks or improper adjustment.

Step 5

Examine your lawnmower's spark plugs if your engine is hard to start, is running roughly, or quickly dies out. If your spark plugs appear worn or damaged, simply replace them.
