The Engine Isn’t Starting
The Kawasaki engine isn’t starting – is this your issue?
We know why it happens with many lawnmowers. The reason is we need to understand there’s a proper mechanism for how a machine works.
Various parts contribute to starting the engine. For example, spark plug, ignition coil, starting switch, etc.
If one of these parts fails, the engine won’t start, so you have to ensure that everything is fine.
- First, check the spark plug of the mower; if it seems damaged, repair or replace it as soon as possible.
- The main part on which the spark plug depends is the ignition coil. This part transfers the voltage to the spark plug, and the engine works. If this doesn’t work, you won’t be able to start the engine. So repair or change it if it’s damaged.
- Check the starting switch when both of the above things are working well. The issue must be because of the button. Luckily, you can easily change it.
- You should also check and replace the primer bulb. It might be broken or worn out, so the mower isn’t starting.
The Engine Stops After a Few Moments
Imagine you enter the key in the mower, push the start button, and the mower also starts but only for a few moments.
Then it stops suddenly; it’s indeed a bad and frustrating situation, but not for you because we’ll share how you can solve it.
First, identify why it’s happening, whether the carburetor is clogged or the issue is with the fuel cap.
To pinpoint the exact issue, you need to check both things thoroughly by following our guide below.
Fuel Cap Issue: You can check the fuel cap with a little test which you can see below.
- Remove the fuel line and take out all the fuel in a container.
- If the fuel isn’t coming out and stops halfway even after removing the fuel line, the issue must be with the fuel cap.
- Once you identify the issue, change the cap or clean it if it’s tight.
Carburetor Issue: The second issue might be the dirty carburetor. The carburetor helps in starting the engine; if it’s dirty or damaged, the engine won’t start.
- Therefore, make sure to clean the carburetor, or if it’s damaged, then replace it.
- You can watch the video below for a better understanding of cleaning the carburetor.
Battery Drains Faster
Another common issue is that the battery drains faster or doesn’t charge, and we think it happens because the engine is taking up too much battery.
But that’s not always the case, at various times, the battery itself creates issues.
The solution to the battery issue is you need to know about its two common causes: the voltage regulator and the stator.
- The first cause is the voltage regulator. Its purpose is to provide voltage to the battery from the alternator. When it fails to provide the voltage, the battery drains faster.
- In this type of scenario, you have to do a test to check the voltage regulator. If the voltage regulator is at fault, replace it to protect the battery.
- The second cause is the faulty stator. The function of the alternator is to create a magnetic field and then convert it to an electric current. If it’s not working well, the battery will create a lot of issues.
- The simple solution we’ve found is to check whether it’s really at fault via a small test with a multimeter. Then go to any nearest technician to solve this issue.
Watch the video below to understand the step-by-step process of testing the voltage regulator and stator.
The Engine Is Running Rough & Generating Black Smoke
Here comes the fifth common Kawasaki lawn mower engine problem; it’s about the engine running rough and black smoke coming out of it.
Rest assured, we know it seems like a big issue but trust us, it is not.
It happens because the choke rod has a lot of dirt, which creates problems in maneuvering.
You can put down the choke rod yourself, but it’s a one-time solution. For the long term, you have to clean it thoroughly with water, and that’s it.
Once the dirt is removed, it will again start working properly like before, and you won’t face any issues.
Fuel Is Leaking
If you’re having trouble with a Kawasaki engine fuel leak, you’re not alone! This is a common issue.
The reason behind this issue is that some parts of the mower attached to the fuel tank, like the carburetor gasket, fuel lines, etc., get damaged.
The solution is quite simple; we’ll share the name of all of these possible faulty parts. You have to check them one by one and replace or repair the right part.
- Check the carburetor gasket or the entire carburetor.
- Have a look at the fuel lines. If they’re cracked, the fuel will leak.
- Check the float assembly.
- Lastly, you also have to examine the fuel tank.
