lawnmower starts but quickly dies

I have a walk-behind MTD mower. It's been running rough lately (sputtery like it's going to die or difficult to re-start after I stop and empty the catcher) but has worked. Today I can prime it with 5 to 8 pumps on the primer-bulb and it starts right up and sounds good but dies in about 3 seconds. It's also quite smokey when it does start and run. Someone at work told me to add oil and it IS over the full mark but not by much. Could too much oil be the problem?

In working on this I've found the more times I pump the primer bulb the longer the mower runs before dying. Only up to about 8 seconds though. I disconnected the gas line and gas flows OUT of the tank easily (I thought maybe something was blocking the line.

Any thoughts? I'd love to take it to someone to repair but I don't have a way to transport it at this time.

Sounds like you need to clean the carburetor. Too much oil can cause the smoke.
