7 Areas Where Your Spartan Lawn Mower Is Gas Leaking

Although you may detect a gas scent coming from your lawnmower, there isn’t a pool of gas there, and there is no sign of a fuel leak. Finding the source of a leak can be challenging, especially if the wet area has possibly dried up.

A jammed carburetor float, a damaged carburetor gasket, outdated fuel lines, a damaged fuel filter, fuel pump, or gasoline tank, a damaged fuel shut-off valve, or a damaged fuel cap might all cause a Spartan lawn mower to start leaking gas.

Always maintain your mower in a room with good ventilation. Gas vapors are dangerous. As stated in your Spartan operating manual, take all additional safety precautions.

How to Fix a Spartan Lawnmower That Is Leaking Gas

  • Examine the carburetor for leaks at the air intake or in the bowl.
  • Examine the gasoline lines and clamps.
  • Review the fuel filter
  • Fuel pump inspection
  • Examine the fuel shutoff valve.
  • Examine the seams in the fuel tank.
  • Verify the fuel cap seal.

Where the Gas Leak is Coming From on Your Spartan Lawn Mower

Lawn mower Spartan Carburetor

Your Spartan mower’s carburetor is a frequent spot where leaks first appear. This part is where a small amount of gas is kept after it has left the fuel tank.

Over time, the varnish from old gasoline might cause the carburetor parts to stick or the gasket in the carburetor can fail, causing the mower to leak.

Sparta Lawn Mower Carburetor Bowl Gasket

The carburetor’s bottom bowl is where the gasket is found, sandwiched between the two. This gasket resembles a rubber band in appearance.

The gasket keeps the carburetor from leaking into the bowl of the carburetor. Due to its exposure to sharp temperature fluctuations, this gasket is prone to dry up and lose its ability to seal.

The gasket gets hot when the lawnmower is operating and cold when it is not because of its proximity to the engine. When the gasket fails due to the load on it, fuel may leak from the carburetor. When the gasket fails, it needs to be replaced.

Your Spartan lawnmower’s carburetor bowl gasket has to be replaced:

  • Fuel can be turned off at the shutoff valve, or the fuel line can be crimped to stop the flow.
  • Clean the area surrounding the carburetor with a damp rag to prevent dirt and debris from entering the device.
  • The bowl of the carburetor can be removed by unscrewing it from the base. Make sure you have a towel handy to soak up any lingering fuel in the bowl.
  • Take out the worn out gasket.
  • Put in the replacement gasket. To prevent the gasket from being ruined, avoid getting any carburetor cleaning or other substances on it.
  • Put the bowl back on the carburetor and make sure the screw is nice and tight.
  • Clean the carburetor with some rags.

Check the float on your carburetor if the gasket around the bowl isn’t leaking or if you changed the gasket but the leak persists.

Your Spartan Lawnmower’s Float Is Stuck In The Carburetor.

Check the area around the vents for air leaks. If there’s a leak here, it could be because your float got trapped. The float in a carburetor serves as a sort of gatekeeper. It regulates the fuel supply to the carburetor by opening and closing the fuel valve at the appropriate times.

The deposits left behind by stale fuel can make your float get stuck. This prevents the float from controlling the amount of gas entering the carburetor. It’s possible for fuel to keep getting sucked into the carburetor and eventually overflow out of it.

Disassembling the carburetor is the only way to find out why the float is sticking. The carburetor and float may require cleaning, or the float may need to be replaced. Here you will find instructions on how to maintain the carburetor in your Spartan vehicle.

Your Spartan Lawnmower’s Float Needle Is Stuck in the Carburetor.

The float needle may need to be replaced if you inspect it. The gas is continuously supplied to the bowl via the float needle. Needles should be changed if they become stuck.

If your carburetor needle is stuck, you can try tapping the side of the carburetor with a rubber mallet. This may work temporarily, but eventually you’ll need to replace the needle.

You need to know the engine make and model before ordering carburetor replacement parts. Once again, the model and serial number are not on the mower itself, but on the engine housing.

What to Do If Your Spartan Mower’s Fuel Filter Is Cracked or Soggy

If you don’t change your gasoline filter regularly, the fuel might erode and soften it. There is a risk of the plastic cracking and leaking at the joints. The fuel filter should be changed frequently to prevent it from becoming clogged or leaking.

If the fuel filter has softened or has developed a crack that is leaking, you should get a new one. The ends of the filter may be fragile, so take care when removing it from the gasoline lines.

You must reinstall the filter on your Spartan lawnmower with the arrow pointing in the direction of fuel flow.

Your Spartan lawnmower has a faulty fuel pump.

The plastic casing of your fuel pump can deteriorate if you let old fuel linger in it, leading to soft plastic and leaks at the seams. When a vacuum fuel pump starts leaking, it must be replaced.

Ripped Welds in Your Spartan Gas Tank

The tank of your Spartan lawn mower is made of HDPE. Fuel leaks might develop from tank seam failure. When this occurs, a new gasoline tank must be installed.

Turn Off Valves for Gas and Oil on Your Spartan Lawnmower

Unfortunately, fuel shutoff valves often develop leaks. If you discover that this is the source of your fuel leak, you will need to replace it.

Your Spartan Lawnmower’s Antiquated Fuel Lines

Eventually, the fuel lines in your car will dry out and need to be replaced. As a result, there is a risk of breaking and leaking. The clamps used to fasten the fuel line to the fuel components may have also caused punctures in the fuel lines. When these clamps break free or rupture the line, water leaks out.

Mower fuel lines that have dried out or cracked should be replaced. If your mower arrived with pinch-style clamps, now is a good opportunity to upgrade to a worm gear clamp.

Since the worm gear clamps do not physically compress your lines, they are less prone to allow water to seep through.

You have a leaking fuel cap on your Spartan mower.

Maybe the gas cap’s seal has deteriorated. During operation, gas circulates within the tank and can escape via the cap if it isn’t properly sealed. If you still detect a fuel odor after checking the aforementioned components, the fuel cap seal may be at fault.

Gasoline evaporates, leaving no visible sign of a damp spot, thus you may have missed the one that formed around the fuel cap.

With the fuel cap on, you can check for leaks by gently rocking the mower back and forth, which will cause petrol to splash up to the cap area. The appearance of a wet spot on the gasoline cap is a warning sign that it needs to be changed.
