I Can’t Start My Push Mower

It is quite frustrating to take your lawnmower out of the garage and find that it simply won’t start. Although this problem is common, it can usually be fixed quickly and easily if you know where to look. It is possible for lawnmowers to lose power for a variety of reasons. These include running out of fuel, dull spark plugs, a clogged carburetor, a broken clutch, and damaged gears.

In order to fix your mower, you must ensure that the air filter is not clogged. This could be caused by a dirty spark plug, a damaged safety cable, a clogged deck, or contaminated gas. Get the grass guzzler up and running quickly by following these steps I can’t start my push mower.

The lawn mower won’t start

It’s possible that the fuel flow to the engine may be inefficient if your mower won’t start.

• It usually occurs when debris collects and blocks key components of the fuel intake system, such as the throttle, primer button, carburetor bowl, and fuel filter.
• Fuel pump malfunction.

A clog of this kind makes it difficult for gas to flow efficiently to the plugs.

Please help! After winter, my lawn mower won’t start

Again, summer is here. You drag the mower out of storage and it won’t start. Once it starts, it won’t shut down. That’s standard!

This article outlines a ten-point checklist to help you get your mower started. If that doesn’t work, you will learn more about fuel, oil, ignition system problems, carburetor fault-finding, checking for incorrect compression, and other issues that may be preventing the engine from starting.

Please note that the second part of the two-part guide covers more advanced troubleshooting for four-stroke gasoline (petrol) engines. You might want to kick things off by checking out part one, which is a 10-point quick troubleshooting guide:

Is my lawnmower turning over but not starting?

The most common reasons for your mower not starting are low fuel, a broken gas valve, or a bad choke. Spark plugs from brokers could also cause the problem. When the fuel pump does not provide fuel to the ignition system, you may need to replace it as well. 

 

Test of the gas shot

It is imperative to narrow down the search area so we can quickly find the problem. Fueling faults cause most mowers to not start, so we begin by testing the gas. If you like, you can consider this a round of elimination. A test like this bypasses both the fueling system and the ignition system, simultaneously testing each.

This test can only be performed with fresh gas, so remove the air filter before starting. A test like this won’t work if the gas isn’t fresh. Drop a bottle cap filled with gas into the carburetor. Your mower should be able to start normally when the choke is all the way up.

The bottom line is that the lawn mower won’t start

The fact that your lawnmower is not starting is certainly a frustrating situation. It’s normal to start asking questions when your mower doesn’t work. The first thing you probably think of is taking it in for service. Before you do that, you should try to resolve the issue yourself. In many cases, you can fix the issue and make the lawnmower work again. 

Getting an old lawnmower started

Depending on how long it has been since you last used your mower, it may take some time to get them started. Most of the time, when you store a lawnmower for a long time, moisture will form in the fuel tank. In addition to diluting the fuel, water in the tank can also cause the spark plugs to not work properly. In this case, we recommend taking out the fuel tank and trying to remove any excess moisture before using your lawnmower.

You can also take these steps if your lawnmower starts, then die. Fuel left in the tank over the winter could be the culprit. Under no circumstances should you drain the fuel tank if you suspect this to be the case. As a result, gum and varnish can gather inside the engine. Furthermore, water may be drawn in at the same time, causing widespread damage.

If your lawnmower’s fuel tank is empty, try adding STA-BIL Fuel Stabilizer. The additive prevents gasoline from breaking down. Let the engine run for a few minutes. Stabilizers should work if degraded fuel is to blame.

Problems caused by contaminated gas

If your mower won’t start, it’s probably because of contaminated gas or a dirty carburetor. When ethanol blend fuels are left in a mower over the winter, they clog carburetors.

Ethanol attracts moisture, and moisture corrodes carburetors. Use a fuel stabilizer; it will keep your gas fresh and prevent clogging for up to two years.

Using Sta-bil gas treatment at the end of the season eliminates carburetor gumming and cleans the fuel system. Add 1 ounce of stabilizer to 2.5 gallons of gas, and you can use it in all gas-powered engines, even 2-strokes.

Check out the stabilizer I use on my “Small engine repair tools” page, and here is a video on using one.

Conclusions

The frustration of pulling the lawn mower starter cord only to hear the motor sputter and die can be agonizing. Rather than hauling the mower to a repair shop or even leaving it curbside for bulk trash pickup day, the mower could likely just need a simple repair I can’t start my push mower.

Give one of these easy, cheap fixes a try before you open your wallet. Once one of these fixes works, you’re no longer excused from cutting your lawn. Prepare your lawn for summer by getting out there!
