surging motor on John Deere 14PB mower

I have a John Deere mower with Kawasaki engine. It is 26 years old. I have never had any trouble with it in all that time. Recently the motor began to surge - up and down. I have thoroughly cleaned the carburetor; I have made sure there is no air entering between the carburetor gaskets; I have tested to see whether the air filter could be the problem; and checked to see if there is adequate fuel flow. The engine starts each time without any problem. The fuel is fresh. Everything appears to be in order; however, the engine continues to surge.

Has anyone experienced the surging-engine problem on their JD mower and found a solution?

Let me know.

Mark,

Thank you for your quick reply. The links to which you directed me concern cleaning the carburetor and making sure the air filter is not impeding the flow of air. I have done these things; however, the motor continues to surge. It is possible, despite my best efforts, that there is something lodged in one of the small holes that permeate the carburetor and that I have not been able to clean out. I have taken the carburetor apart as far as it can be done and I have sprayed every hole and I have soaked every part in carburetor cleaner; however, after I put it all together and reattach it to the mower, the surging problem persists. Is it possible that in a 26 year-old mower, there could be some other explanation for the problem? Could there be some internal component in the engine itself that may explain the surging?

Getting a new carburetor for a 26 year-old mower is not an option because of the expense -- about $200. I might as well buy a new mower. For the price of a new carburetor, I could be half-way to a very good new mower.

Thanks,

ajp
