Thank you for your question and I understand your concern.

If the cylinder is filling up with fuel, do not attempt to start or run the engine until you correct the problem. The oil and oil filter will need to be drained and replaced after repairing the carburetor. When a cylinder fills with fuel; the fuel will migrate past the rings and contaminate the oil and you could cause the engine to seize due to the lack of proper lubrication. If the fuel fills the cylinder, it can cause a hydraulic effect and prevent the piston/engine from spinning over when it reaches the compression stroke.

The float, needle, and seat are not regulating the fuel level in the carburetor. When this happens, the gas will run into the cylinder and can keep it from turning over if the cylinder is filled with fuel. To cure the problem you will need to take the carburetor back apart and most likely need to replace the needle valve part #696136 and the fuel bowl transfer tube part #698780. If any of the seals/o-rings are leaking located above the fuel transfer tube, it can also cause the same issue.


After you have the carburetor taken care of, remove the spark plug, and turn the engine over by hand. This will remove any fuel left in the cylinder and then replace the oil and filter. Once you have the fuel cleared out leave the spark plug out and change the oil. Then refill the engine and reinstall the spark plug. Now check the operation of the tractor.

Forgot to mention that upon checking the oil it smelled of gasoline and was extremely thin. Model 917.289081. I got this mower refurbished but it's had light usage and I'm not happy.
