Common Reasons Why Your Snowblower Leaking Gas
Snow blower leaking gas? This blog provides information on how to troubleshoot a snow blower and the most likely defective parts associated with this problem.
If your snow blower is leaking gas, here are the 8 most probable causes.
1.Worn carburetor bowl gasket
If the leak appears to be coming from the carburetor, it is likely that the carburetor bolt gasket is worn out or missing. You can replace the gasket with a new one to fix the problem.
2.Defective float assembly
Various float assembly components inside the carburetor bowl can be defective as well. The float needle or the float itself is damaged, the carburetor may continue to fill with fuel until it overflows. You should be able to stop the leaking by replacing one or more of these components.
The leaking fuel could be coming from the carburetor itself. Over time, the carburetor can develop cracks, due to the vibration and heat when the snow blower engine is running. If the carburetor shows any sign of damage, you will need to replace it with a new one.
4.Damaged fuel filter
It is also possible that the leak is coming from a crack in the fuel filter housing. You need to inspect the fuel filter for any damage and replace if necessary.
5.Leaking fuel line
One or more of the fuel lines may have developed a leak as well. You should replace the fuel line with a new one, instead of attempting to repair the old line.
6.Damaged fuel pump
A fuel leak could also be coming from a damaged fuel pump. You need to check the component for cracks or pin holes in the body and make sure the fuel lines and pulse line fit tightly on the fuel pump.
7.Brittle primer bulb
The primer bulb draws fuel through the carburetor when pushed to primer the engine when first starting. Over time the rubber can become brittle and crack, causing the bulb to leak gas. Installing a new primer bulb will fix the problem.
8.Broken fuel shut-off valve or solenoid
Finally, you should inspect the fuel shutoff valve or shut off solenoid for leaks. You also need to confirm the fuel shutoff lines fit tightly and are free of cracks or tiny holes.
