Pulsar Generator Fails Under Load (6 Causes)

The generator should be turned off and the engine troubleshooted when it fails to perform as expected.

If you keep running the generator like way, you risk ruining it and whatever else you have hooked up to it.

When the generator’s load exceeds its capacity, when the carburetor is unclean, when the fuel filter is blocked, when the air filter is clogged, when the throttle is jammed, or when the spark arrestor is clogged, a Pulsar generator will bog down.

The engine must cool down before the spark plug wires may be removed. Use this in conjunction with the instructions in the manual to reduce the likelihood of significant injury.

Before diagnosing, repairing, or operating, be sure you’ve read and understood all of the safety recommendations in the equipment’s operator’s manual.If you don’t feel confident in your ability to conduct the repair safely due to a lack of experience, training, or health, it’s best to call in an expert.

Pulsar Generators Bog Down Under Load Because of This

Overloading the Pulsar Generator Size

The generator may stall if you try to run more appliances than it was designed to handle. Pulsar manufactures a wide range of generators for a variety of uses and power requirements.

Before looking for potential problems, make sure your generator isn’t overloaded by comparing the wattage of everything you’re powering with the manufacturer’s specifications.

The total wattage of everything you’re trying to power at once must be below the generator’s maximum safe load.

Most generators will have a label detailing the maximum wattage at which it may safely operate.

Determine the watts by using these guidelines:

  • Most electrical equipment will have a label with the wattage listed on it.
  • It takes more power to get some motors going. In this scenario, the required wattage can be determined by using the initial wattage. A generator’s beginning wattage is the maximum amount of power it can provide for a short period of time, such as when an appliance is turned on.
  • To get a total, add up the wattage of everything that will be hooked into the generator at once.
  • The combined power consumption can’t exceed the generator’s wattage rating.

Keep the generator’s load below its rated capacity. Turn off the power source if the machine stalls.

Take out everything that’s plugged into the outlets. To add more items, start the generator over.

Pulsar Generator With an Unclean Carburetor

The carburetor is necessary because it controls how much gasoline is added to the air mixture before combustion. A clogged carburetor caused by old fuel is a common cause of engine sluggishness.

Varnish left behind by old fuel can suffocate fuel lines. If there isn’t enough fuel, there won’t be enough of a fuel-air explosion to start the engine.

To restore functionality, a clogged carburetor requires removal for cleaning or rebuilding.

Before cleaning the carburetor, it’s a good idea to document the disassembly process so that the tiny components may be replaced in their proper locations.

Take the generator’s carburetor off. Use a carburetor cleaner to get rid of as much gunk as possible. A carburetor rebuild kit can be used to replace any worn or broken components.

Carburetor installation follows cleaning and fixing.

If you don’t feel comfortable dismantling your carburetor and cleaning and rebuilding it yourself, you may always buy a new one. If cleaning the carburetor doesn’t fix the problem, you may need to replace it.

A Pulsar Generator With a Clogged Fuel Filter

To prevent wear and damage to the Pulsar generator’s engine, a fuel filter is installed in the fuel system. Over time, it might become blocked and restrict fuel passage to the carburetor.

An inline filter could be installed in the gasoline supply lines. The fuel filter is probably located at the bottom of the fuel tank or concealed within another inaccessible fuel component if you can’t find it.

Seek advice from a Pulsar service center if you have questions about whether or not a gasoline filter is installed in your vehicle and, if so, where it might be located.

A Pulsar Generator with a Clogged Air Filter

Your generator cannot function without the air filter. The engine is protected from dirt and debris by only receiving clean air. Without an air filter, debris can clog the engine’s air intake and cause expensive damage.

If you operate your generator frequently or in dusty environments, you should replace the air filter more frequently than once a year.

You shouldn’t just change the air filter when it gets dirty; you should also clean it regularly. To keep the filter in good shape and free of dirt and debris between changes, it should be checked on multiple occasions.

Filters can become so clogged with dirt that air can’t get to the engine if they aren’t cleaned and replaced periodically. It can cause the engine to overheat, stall, and sustain severe damage.

Before using, make sure the air filter has been cleaned or replaced if necessary. To clean your Pulsar, use the guidelines included in the user handbook.

Here are some notes about maintaining a foam air filter. If your generator has a filter of a different kind, check the manual to see how to use it.

Cleanse a Pulsar generator foam-style air filter

  • Take out the filter and throw it away.
  • The air filter housing and cover should be cleaned of any lingering dust or debris. Keep the air intake free of debris.
  • The foam filter should be checked for wear and replaced if necessary.
  • The filter can be cleaned with soapy water and rinsed until the water comes out clear if it is in good condition.
  • To dry the filter, simply squeeze it.
  • The foam filter may need to be soaked in oil or gas, depending on the model. Remove any surplus fluid from the filter by squeezing it. If you are unsure about the fluid that should be used to coat the filter in your model, I recommend consulting the handbook.
  • Put the air filter in place.
  • The air filter cover must be reattached.

Cleanse a Pulsar generator paper air filter:

  • Take out the filter and throw it away.
  • The air filter housing and cover should be cleaned of any lingering dust or debris. Keep the air intake free of debris.
  • Check the air paper filter. Tap the filter to dislodge dirt, allowing it to fall through the openings. If the filter is unclean, torn, or no longer effectively seals the air intake, a new one should be installed.
  • Put the air filter in place.
  • The air filter cover must be reattached.

Stuck Pulsar Generator Choke

When the throttle isn’t readjusted once the engine heats up to let enough air get to the engine, the generator can stall for lack of ventilation.

By reducing the amount of air entering the engine, the choke makes the fuel run rich. A cold engine cannot be started without this. If the choke isn’t released after starting the engine, it can cause it to stall.

One possible cause of this is failing to turn off the engine’s choke once it has warmed up. A jammed choke or faulty switch/dial (depending on model) used to start the generator are two more possible causes.

Pulsar Generator with a Blocked Spark Arrestor

Installing a spark arrestor screen on a Pulsar generator reduces the risk of sparks and other high-temperature debris escaping the muffler. This will lessen the likelihood of fires and burn casualties.

If carbon deposits prevent hot exhaust air from passing through this metal screen, the generator will operate roughly or even shut down.

Wait until the muffler has cooled down before attempting to remove the spark arrestor for cleaning. Check the condition of the spark arrestor screen by removing it.

If there are any tears or holes in the mesh screen, you should get a new one.

If the screen is still functional, you can clean it with a commercial solvent or brush off the soot with a small metal brush. Return the screen to the muffler after cleaning it.
