It can be caused by blocked (dirty) carburetor passages, faulty carburetor diaphragm or weak governor spring. Dirty or binding governor linkage can also cause the problem. However the most common cause of surging (revving up and down) in small engines such as those found on lawn mowers, is vacuum leaks. The gaskets often dry up when the engine is stored over the winter with an empty gas tank and then leak air into the carburetor. Prevent this by putting fresh gas in the tank with a stabilizer additive before storing for the winter. To test for bad gaskets, spray starter fluid around the carburetor gaskets while it is surging. If it stops surging while you spray, you have your answer.
