Hello Rick,
Your statement above indicates you already once before posted a question on this topic. I have not located that question in the list of topics here. If I could find it I would have merged it and this one together.

In reply to your question below, sounds like the carbs float isn't shuting off the flow of fuel. When this happens, the combustion chamber fills with fuel and some of the fuel passes by the piston rings and gets into the crankcase, etc.

To resolve this problem, the carb must be removed, cleaned out, the new parts in the carb kit installed and the float tested to determine if it has a hole in it. Once the cause of the problem is located and corrected, the carb can be reinstalled and the problem your describing will be solved.

I also edited the topic to clearify the problem.

Thank you so much for your reply. I was told that it may be a stuck valve or worse a broken valve. I will get a rebuild kit and when I am finished I will tell you the results.

Thanks again.

I agree with Tom, it is definitely a carburetor problem, no broken valves to worry about.

Thanks Guy's for your help.

It was just that! I took my carb off, went to my local small engine repair place to purchase a new carb rebuild kit. The owneer told me that I did not need a rebuild kit. He showed me what to take apart and clean. After a very rigourous cleaning, I placed the carb back on and the first bump of the key it fired right up. I don't remember my mower running this good when I first bought it.
Happy mowing and keep up the good work!

To be safe, you should change your oil, now that
the fuel problem is cured.

I have changed the oil but thank you for the reminder,yes it would have been devistating had I not removed all of the fuel that had gotten into the oil.
I only wish I had done the carburator a few years ago. The tractor has been spitting and sputtering for the last three years.
Now it runs like a sewing machine.

Thanks for all the help.
