The number you provided is actually the serial number. I was going to need that to determine the warranty, so including it was good.

Based on the serial number the production date is July 29, 2004. That would put the tractor outside the manufacturers 2 year warranty period.

In most cases where there is gas coming from the muffler itself it's due one (or more) of a few things. If the key was left in the "run/on" position that can happen; I actually see that happen quite frequently. Because the mower will shut itself down when you come off the seat, people will stop the tractor and get up letting the mower shut itself down. But because the key is still on, the fuel shutoff solenoid stays active allowing gas to pass through the engine. It will also run the battery all the way down if left that way for several days.

If the float it stuck in the carburetor it can also cause the same condition. Make sure to check the oil in the engine because normally if you oil coming from the muffler you will also have oil mixed in with the gas. If the engine is ran like that it can cause a lot of problems.

If the vent on the fuel cap is plugged up the heat from it being summer can cause the gas fumes to expand and that will push fuel past the valve in the carburetor causing a fuel flood situation.

It is upsetting when a needed piece of equipment develops problems. Normally the warranty information in the owner's manual would tell you how long the warranty is in effect. The exception would be if you purchased an extended warranty agreement. I tried to locate the manual for your tractor. If you have the model number handy to recheck, just enter it into the link below for online access. The expert may be able to provide an easy fix. Hope this helps!
