Primary causes of surging for a generator under load include:
- Stale Fuel
- Clogged or Restricted Main Jet
- Missing or Detached Throttle Spring
- Float is Closing the Float Needle Valve Prematurely
- Any Filter or Screen from the Carburetor to Inside the Gas Tank is Clogged or Restricted
Why is my Generator revving high?
Generators produce a revving sound when the carburetor becomes so dirty that it begins restricting the amount of gasoline entering the engine. The gasoline in a carburetor becomes gum and varnish in the long run, creating a blockage. If dirt invades the carburetor, it can produce similar results. Generator Revving High – Why?
Why does my Generator surge at idle for 10 minutes?
Cold weather can cause your generator to surge at idle sometimes for 10 minutes or more until things really start warming up. When the temperature is cold, gasoline does not vaporize quickly at all and you may need to leave your unit on half-choke for a long time until it reaches that point.
What can cause a generator to stop working?
Your generator was designed to use specific fuel sources, and anything else may cause operation problems (and irreparable damage). Failing capacitor or other components. A failing, damaged, or aging capacitor can create wild fluctuations in the regulation of power supply and distribution.
What should I do if my generator surges?
The first thing you should check before you even dig into anything is the quality of your gasoline that’s in your generator. If you have gasoline in the tank that has not been stabilized and has been in there for more than a couple months then fuel quality is likely a major issue in the surging.

Why does my generator keep pulsing?
There are numerous causes for generator surging, including: Incorrect fuel use, fuel levels, and fuel quality in gas/oil generators. Your generator was designed to use specific fuel sources, and anything else may cause operation problems (and irreparable damage).
Why does my generator not run smoothly?
A clogged carburetor is most often due to leaving fuel in the generator for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and cause the engine to stall or run roughly.
What causes a generator to hunt?
Usual causes of generator hunting and surging – solutions Fuel blockage or restriction: Firstly, check filters and fuel quality. Fuel pump – intermittent fault: Check for leaks or lack of fuel. Machinery has suddenly started up and caused a wild spike load.
What is the common problem of generator?
The single most common generator problem is neglected maintenance. Think of the engine on an industrial generator the same as you would the engine in your car. It is well known that there are going to be problems if you don't check the engine's components for wear and tear in addition to preventative maintenance.
Why is my generator power fluctuating?
Damaged components within your generator could be the culprit in your search for the cause of surging. Damaged capacitors could be one example of a single component preventing your generator from properly generating and distributing power, leading to wild fluctuations in the regulation of power supply and distribution.
How do you clean a generator without removing a carburetor?
Yes, generator carburetor cleaning is possible without removing it, if it is not completely clogged. You can either spray a carb cleaner directly inside the carburetor or add a fuel treatment to the fuel tank to remove all dirt and debris.
What causes an engine to hunt and surge?
Engine hunting and surging at idle is usually caused by a fuel delivery, air leak, or governor system problem. Cleaning/overhauling the carburettor, adjustment of the governor, and/or changing the air filer may be required.
Do whole house generators cause power surges?
Power surges: When you're running a high-wattage appliance, turning it off can sometimes cause a power surge. The surge can travel to other devices or appliances. Generators: Yes, whole house generators can cause spikes and surges in your electricity.
Do surge protectors work with generators?
When you use a power strip with a generator, it is always best to use one with a surge protector. Admittingly, most generators provide stable power that is akin to the power you get from your regular household supply, but fluctuations in power can happen.
Why is my generator loud?
Some generators are loud because you have forced them to sit on hard surfaces. The vibrations they send into the ground will multiply their noise levels. But if you place a generator on a soft, padded surface, the padded surface will reduce the noise levels by absorbing those vibrations.
Why is My Generator Making a Knocking Sound?
Like most machines with engines, a bad air/fuel mixture can result in bad timing which , in turn, can cause knocking in a generator.
How Noisy is a Generator?
Portable generators are smaller than backup generators but the noise levels can rise up high as 100 decibels because they do not have noise-cancelling.
How to reduce generator noise?
Invest in attenuators. Attenuators will absorb the sound a generator produces, reducing the noise to acceptable levels.
How many decibels does a generator cut?
You can trust them to cut as much as 15 decibels from the noise levels of a generator. But if you want the best results, you should get a muffler that was made with generators in mind.
What happens if you have fuel in your carburetor?
If you still had fuel in the carburetor when the generator went into storage , that fuel became gum and varnish which is currently restricting the carburetor. This can happen with just a few drops of fuel.
How far away should a generator be from a dishwasher?
A generator is supposed to produce the same level of noise as a dishwasher or vacuum cleaner from seven meters away. The sound should be consistent.
What happens when a generator is surging?
Let’s use some examples. A surging generator often will leave lights burning much brighter, then much dimmer rapidly, causing a sort of flicker back and forth. In machinery, this can also come as drastic changes in pace as well; such as a fan running faster and then slower for no obvious reason.
What causes gas generators to fail?
Incorrect fuel use, fuel levels and fuel quality in gas/oil generators. Your generator was designed to utilize specific fuel sources, and anything else may cause problems in operation (and irreparable damage).
What Is Surging?
Surging refers to a generator (or other electrical component, machine or device) displaying clear fluctuations in behavior at intervals. These intervals can follow a clear pattern, or can be completely random. What exactly does this mean? Let’s use some examples.
How long do generators last?
Generators are built to last an exceedingly long time, but sadly, nothing lasts forever. If your generator is experiencing surges, and is getting on in years, it may well be time to consider replacement.
What happens when a capacitor fails?
Failing capacitor or other components. A failing, damaged or aging capacitor can create wild fluctuations in the regulation of power supply and distribution.

The certified experts at Kolb Electric have a strong history of handling generators, and today we bring you one of the most common complaints among generator-owners: power surges.
Why does my generator surge when idle?
By far the most common mechanical reason why a generator surges at idle is due to the idle jet being clogged. During the idle cycle, which is just a phrase meaning the components of the carburetor that are functioning while the generator is at idle instead of having a load on it, the idle or pilot jet is responsible for allowing the correct amount of gas into the combustion chamber while the throttle butterfly valve is closed and the generator is running on idle.
How to access idle jet on generator?
Luckily, the idle jet is generally very easy to get to and you might be able to access it without having to remove the entire carburetor from the generator. If you look at the photo below you can see where the idle jet is located and you’ll likely only need a phillips or flat head screwdriver to access it.
When is Surging Dangerous For My Engine?
If you’re hearing loud “pinging” or “knocking”, almost like metal is striking your piston in the combustion chamber, then you’re going to be in trouble.
What does it mean when gaskets are clogged?
This can mean that there is actually too much air being sucked into the combustion chamber through the carburetor (say, through a torn gasket which creates a vacuum) and the appropriate amount of fuel (if that vacuum leak didn’t exist), or it can mean that the amount of air is correct but gasoline is being restricted by a clogged jet and is not enough.
What happens if you leave old gasoline in the tank?
If you do have old gasoline that was left in the tank which has now started to turn to varnish, then you’d likely have the next problem as well which is a dirty carburetor and especially a clogged or restricted idle jet.
What does it mean when an engine is pinging?
Though this is relatively harmless, it may lead to permanent engine damage if there is excessively loud “pinging” or “knocking” as this will indicate detonation occurring during the combustion process. An engine that is surging at idle is also known to be “hunting”.
