Cub Cadet 19HP Kohler Lawn Tractor will not start

[Wayne G]

Engine turns over but does not want to start. Replaced battery, spark plug, fuel filter. There is spark at plug , but even with gas injected into air filter inlet no ignition, Battery dies with only 1-2 minutes of cranking.
Any ideas would be greatly appreciated.
Thanks

Have you cleaned the carb? is there overhead valves on engine?

Check the starter. Mine was always hard to start from new. I replaced it and it very obvious that the factory starter was not correct from the start. Now it cranks beautifully. If your's cranks with difficulty (not rapidly), that may be the issue.
