Why is Your Generator Blows Black Smoke
If you want to know the reasons behind this red flag, here are some of the causes of black smoke from your generator.
One of the major causes of why your generator is emulating black smoke is the carburetor. When your carburetor is dirty or requires services or needs changes, it will result in your generator blowing black smoke.
2. Close Choke
Whenever you want to start your generator, it’s instructed you to close the choke. And after starting, you should return it open. But in cases where you leave the choke closed and didn’t return it whenever your generator starts might result in it emulating black smoke.
3. Bad Fuel
Bad fuel can damage your generator, and it can as well cause your generator to smoke. When your generator fuel is bad, especially if it’s dirty, it passes through the generator pipe into the carburetor. And later affects the generator’s carburetor and makes it blow black smoke.
4. Limited Fuel
If you don’t have bad fuel in your generator’s tank, then there might be limited fuel in your generator’s tank, which might also cause your generator to smoke black.
5. Bad Filter Or Dirty Filter
All generators have a filter. The filters are there to filter the air passing through the carburetor. And if the filter is bad or has caused dirt, it might result in your generator removing black smoke.
So, whenever you notice that your generator is blowing up black smoke, this is why it is doing so. After knowing the causes, let’s look at what will result if you don’t solve the problem fast before talking about how you fix it.

However, whenever your generator is blowing out black smoke through its exhaust, and you do not fix it in time, it will result in your generator not working effectively. For instance, it will make your plug not function again and not make your generator start.
Your generator can also start developing a fault of not powering all your appliances as it is supposed to power the appliances.

After knowing the causes of generator black smoke and what will result if you don’t fix it in time, here’s a guide on how to fix your generator whenever it blows out black smoke through its exhaust.
1. Check Your Generator Air Filter
If you want to fix your generator whenever it’s blowing out smoke that is black through its carburetor, the first thing that you need to do is to check its air filter, whether it is dirty, bad, or needs changes.
If you check and it is dirty, you wash it thoroughly using good fuel. And if it’s bad, you change it or don’t use it anymore.
2. Clean Your Spark Plug or Fix a New One
When you removed the plug, you noticed it was black. Then you clean it, fix the air filters, and start your generator.
After minutes, turn off the generator—remove the plug—check if it’s still black.
Suppose it is(go to the next step). But if it isn’t black, your carburetor has stopped blowing out black smoke.
3. Check your fuel tank if You Have Bad Fuel or Limited Fuel
If you have cleaned your air filter and it’s still removing black smoke, you must check your tank for any bad fuel. If you notice your generator is bad or dirty, you should change it with new and good fuel.
Also, if you checked and there’s limited fuel in your generator tank, you should add more fuel.
4. Service Your Generator Carburetor
The next thing you should do after trying all recommended methods and it still doesn’t stop is to service the carburetor. Besides, as a generator novice, you won’t know how to service a carburetor. So, it will be best if you contact your generator mechanic.
Sometimes, before your generator Ir can stop this issue, it will be okay if you change the carburetor and fix a new one. But that will be after your generator mechanic has detected that your carburetor won’t work anymore and needs to be changed.
5. Open Your Generator Choke When Working
Lastly, if you have done all the listed methods, you should open your generator’s choke when working. This doesn’t mean that it should be left open if you want to start your generator because it won’t start.
If you start your generator and you noticed the problem still persist, then the carburetor has developed a fault, and you should consider changing it. However, you can get another quality carburetor from Amazon or any other online marketplace.
