The problem with the fuel is likely due to varnish that has formed in the carburetor bowl. Ignore an empty "looking" fuel filter, it does not indicate a problem (except if the tank is empty, then it means the tank is empty). Don't bother changing the spark plugs either. If they were new (or almost) last fall, they're still good. Spark plugs do not get "moldy" from sitting. Since you are able to get the engine started, you can try adding Seafoam fuel treatment to the fuel and running the engine long enough to allow the Seafoam to begin cleaning out the varnish. You could speed up the cleaning process by taking the carb bowl off and cleaning the jets with spray carb cleaner. Even if you do that, you still need the Seafoam added to the fuel. Also, be sure the fuel tank cap vent is not clogged. **** When I went to start it, battery was dead. I had it recharged successfully***** Successfully??? That may not be true. It is very common for a battery that has been dead for some time, to be "recharged" and subsequently suffer total failure or very reduced capacity. You may think the battery came back to life, and it may show 12 or more volts immediately after being charged, but that voltage proves nothing about the available power the battery has (or doesn't have). The true measure of a battery is the load test. Have the battery load tested by an auto parts store or a good auto shop. It is also possible that your charging system is not working at full output. I doubt the stalling and slow RPM are related to the electrical system UNLESS........the engine uses "battery and coil" ignition. Tell us what engine your tractor has, and post the engine model and type numbers, or model and spec numbers, whichever apply to your particular engine.
