why is my Craftsman Lt 2000 tractor leaking gas?

Craftsman lt2000 model # 917-273143 w/a Kohler Pro 17HP OHV engine. This unit is appx 7 years old & more than not provides very good service. After filling plastic gas tank yesterday after mowing yard, it began to leak gas dripping to ground rather rapidly from beneath what seems to be the muffler assembly. Although I have removed shield from beneath muffler assy so that I could hopefully see what might be problem, no luck yet. I had to temporarily disconnect fuel line before carb and turn up in a held/locked position to stop the gas flow / leak issue. Any thoughts please?

Thank you for your question.

I am sorry you are having a problem with the tractor. I suspect the float in the carburetor is not regulating the fuel level in the carburetor. you will need to clean or replace the carburetor.

To access the float follow the steps below:

Clamp off the fuel line with a pair of vise grips.

Disconnect the wires that go to the fuel shut off solenoid

Unscrew the solenoid.

Drop the float bowl.

Using a pair of needle nose pliers remove the float hinge pin

Being careful not to loose the needle remove the float.

Shake the float and listen for a liquid sound from inside it.

If there is a liquid sound inside the float must be replaced as it has a hole in it.

If there is no sound the float is ok and the problem is in the needle and seat.

Remove the fuel line from the carburetor inlet.

Now spray carburetor cleaner into where the needle goes. This will back flush out any debris.

Then inspect the inside of the fuel line. If it is cracking you need to replace the fuel line and the filter before reattaching to the carburetor inlet.

After you have cleaned the carburetor reassemble the it in reverse order.

Reinstall the float bowl and fuel shut off solenoid.

Reconnect the solenoid.

Remove the spark plug and place a rag near the spark plug hole.

Hold the spark plug wire with a pair of insulated pliers and crank the engine. This will clear out any fuel that has accumulated in the cylinder.

Reinstall the spark plug.

I strongly recommend changing the oil and the filter if your engine has one. If the oil has gas in it will thin the oil out and it is just like running the engine without oil.

I hope this is helpful.
