This article discusses some issues with Toro lawnmowers when they stall after starting.

Spark Plug Problems

Look for signs of wear or damage on the spark plug. If there are any cracks, an electrode is burned away or damaged, or carbon buildup at the electrodes is visible, replace the spark plug.

To determine if the spark plug is defective, use a spark plug tester to see a strong spark between its terminals when you try to start your engine.

If you’re not getting any kind of spark while trying to start your lawnmower off, this indicates that you need to change out your current spark plugs.

However, take note that some parts shops and repair businesses will verify whether a part is faulty by connecting them back into your vehicle first before filling in all costs prior to purchase.

Gasoline That Is Old Or Bad

A clogged carburetor is most often caused by mixing oil with the fuel. This mixture is difficult for the engine to burn completely, leaving behind a sticky substance that clogs the holes in the carburetor and causes it to stop functioning.

A good way to fix this problem is to clean out the carburetor with a cleaner and try using fresh gas next time you’re going to fire up your mower.

If cleaning and replacing fresh gas doesn’t help, either rebuild or get a new carburetor altogether.

Malfunction Of The Fuel Cap

As fuel is used by the engine, the level in the tank lowers. to make up for this, some models of lawnmowers use a small vacuum pump to force air into the tank.

If this vacuum pump becomes clogged or stops working altogether, then a “vapor lock” occurs which prevents fuel from entering the carburetor.

This can cause a severe lack of power and has in some cases caused vehicles to stall out completely.

To determine if this problem is occurring, try loosening or tightening the gas cap as you may have a clogged fuel cap vent. If this fixes your vehicle’s stalling problem it is likely that your fuel cap vent has become clogged.

Carburetor Failure

The carburetor may be clogged. A carburetor may become clogged over time because gas is added to the mower but there are not many adjustments made to ensure that all of the fuel makes its way through the system.

If a carburetor becomes partially clogged, it can cause the engine to stall or misfire, locking up and refusing to turn on. If that’s what happens, don’t panic.

There are things you can try from replacing spark plugs to cleaning out gas lines and more until your mower starts up again with ease, allowing you to take care of all those last-minute garden projects.
