Thank you for your question.  I am sorry you are having a problem with the mower. If the engine was running fine but now runs slower, I recommend checking the linkage on the carburetor. The image below shows how the linkage should be connected. If it is connected correctly, the metal tab that sets the speed could have been belt. If this is the case, the speed has to be reset. The image also has the instructions for adjusting the engine speed. Many customers will adjust the engine speed by ear but the proper way is to use a tachometer. The engine should be set to 3250 rpms. I hope this is helpful.. Please let me know if you need further assistance.   Thank you for using Manage my life.Mark
