Engine vapor lock1/3/2024 Your mower will likely need to be refilled before this product stops working. It helps stabilize fuel for as long as two years, so you’re unlikely to ever have to worry about the condition of your fuel. You can use a product like Star Brite Star Tron Enzyme Fuel Treatment (link to Amazon). This helps increase the lifespan of your gas. One of the advantages of using an ethanol-free gas is that it has a longer shelf life.Īdditionally, get into the habit of adding a fuel stabilizer to your tank every time you fill it up. You can encounter a lot of issues when using gas from your local station pump which I explained in this article. These fuels are meant for larger cars, not smaller lawn mowers. What you should do instead is be conscious of what fuel you’re adding to your mower and avoid fuels that include alcohol or ethanol. Luckily, you don’t need to refill your gas every month. It also increases the risk of vapor lock since the gas won’t burn, allowing it to get hot enough to vaporize instead ( source). In fact, in as little as 30 days, the gas inside your mower will have degraded and become significantly less combustible, and therefore, less effective. That’s right, gasoline can go stale, and it doesn’t take long. Let’s now talk about what you need to do. Luckily, preventing vapor lock is a relatively simple task. Vapor lock is undoubtedly one of the most annoying issues that your lawn mower can face. How To Prevent Vapor Lock in a Lawn Mower This is especially true if it happens during the summer when the heat is already a problem. While the summer heat is the most common cause of vapor lock, leaving a mower near very hot objects such as a working barbeque or fire pit can also increase the risk of your mower developing a vapor lock. Without fuel, the engine either stops working entirely or starts and stalls, both of which can be highly annoying. The fuel can vaporise due to being heated by the engine, by the local climate, or due to a lower boiling point at high altitude.Check out the DynaTrap Mosquito & Flying Insect Trap – Kills Mosquitoes, Flies, Wasps, Gnats, & Other Flying Insects – Protects up to 1/2 Acre (link to Amazon). Restarting the engine from this state may be difficult. This disrupts the operation of the fuel pump, causing loss of feed pressure to the carburetor or fuel injection system, resulting in transient loss of power or complete stalling. It occurs when the liquid fuel changes state from liquid to gas while still in the fuel delivery system.

If the vapor pressure of the bubble is high enough, it will block the fuel and keep it from flowing to the engine. If the fuel in the line between the tank and carburetor is heated enough for the fuel to vaporize, a bubble will form in the line.

Source: FAA Airplane Flying Handbook (FAA-H-8083-3A)Ī condition in which vapors form in the fuel lines and block the flow of fuel to the carburetor. On fuel-injected engines, the fuel may become so hot it vaporizes in the fuel line, not allowing fuel to reach the cylinders. Vapor lock may occur as a result of running a fuel tank completely dry, allowing air to enter the fuel system.
