Why Won't My Push Mower Start? Solution: Mind your Gas!

Ever dread mowing your lawn, anticipating the embarrassment of constantly pulling the start rope to no avail wondering: why won't my push mower start? Have no fear, you've come to the right place, and the solution follows! It is estimated that 2/3rds of repair orders for small engine equipment stem from fuel-related problems! By sensibly managing your gas, you can avoid many of the pitfalls related to improper fuel storage, both within the gas tank, and outside your lawn mower.

Fuel-related problems are the number one cause of no start complaints!

This staggering statistic highlights a common issue that many homeowners face, but the good news is that the majority of these fuel-related issues can be avoided entirely with proper fuel storage and maintenance practices.

Understanding these practices can not only save you time and money but also ensure that your lawn mower and other small engine equipment operate smoothly and efficiently.

It is imperative that you understand that the shelf life for gas is approximately 3 to 4 weeks. This means that if you purchase fuel in bulk, it is likely to degrade before you have the chance to use it all, leading to potential starting problems. The best practice is to not purchase more fuel at one time, than will be consumed within this time frame. Always store your fuel in a fire-approved gasoline container, which is specifically designed to handle flammable liquids safely. Additionally, make sure to keep these containers in a cool, well-ventilated area. The cooler the gas is kept, the slower it degrades, which can significantly extend its usability. Ideally, try to purchase only what you need for a few mowing sessions, which will help in maintaining the quality of the fuel.

Furthermore, small engines are particularly sensitive to the quality of fuel they receive. One of the most detrimental contaminants is water. Small engines absolutely hate water in their gas tanks! In fact, water contamination can cause a unit to not start at all or run incorrectly, even if it manages to start. This is why it is wise to not leave lawn mowers outside and uncovered, as many gas caps are vented with small holes where rainwater can accumulate and enter the gas tank. This seemingly minor oversight can lead to major headaches, including costly repairs.

To mitigate these risks, consider using a fuel stabilizer, that can help prevent moisture buildup and keep the fuel in good condition for a longer period.

Furthermore, ethanol found in gasoline attracts moisture, and when left in your lawn mower's gas tank for extended periods, forms layers of water that sit at the bottom of the gas tank, due to 'phase separation'. Water in a gas tank will cause the unit to fail to start, as well a corrode metal gas tanks. Never leave gasoline in a gas tank for an extended period as the ethanol forms a varnish within the fuel-delivery system causing the machine's carburetor (the device responsible for mixing fuel and air in order for the engine to fire) to not function, as it becomes plugged.

In addition to proper fuel storage, regular maintenance of your lawn mower is crucial. This includes checking and replacing the air filter, spark plug, and oil as needed. Neglecting these components can exacerbate fuel-related issues and lead to a frustrating mowing experience. By taking the time to perform these maintenance tasks and being especially mindful of how you store your fuel, you can significantly reduce the likelihood of facing the dreaded scenario of a stubborn mower that refuses to start.
