Most Frequent Issues With Champion Generators
1. The Champion Generator Is Unable To Start
Combustion engines can’t get going without air, fuel, and a spark. The combustion process begins when the air and fuel mixture is ignited by a spark.
If your Champion generator won’t turn on, check first for anything that could be preventing the engine from reaching to its starting position.
If you have an electric start generator and are having trouble getting it to turn over, check the battery, ignition switch, and starter solenoid.
Check for a blocked fuel system, old fuel, defective spark plugs, a faulty ignition coil, or a plugged air filter if you can get the engine to turn over but it won’t start.
| Cause | Reason for Problem | Solution |
| A lack of fuel. | The gas tank is empty. | Refill the tank as necessary. |
| Used or stale fuel | Over time, fuel loses its effectiveness, and it can block the fuel system and damage its components. | Empty the gas tank. Put in new gas and a fuel additive like Sea Foam to keep the gas stable and the engine clean. |
| Faulty fuel-tank vent | If the fuel tank vent becomes blocked, the tank will develop a vacuum, severely limiting fuel delivery. | Unclog the fuel tank’s ventilation system. |
| Lack of spark | A spark plug that is either too dirty or damaged, has a poor connection, or is improperly gapped. | Install a new spark plug with proper gapping and tightening all connections. |
| Incorrect ignition coil | If the ignition coil is faulty, there will be no voltage sent to the spark plug, and the generator will not start. | Check for and repair a faulty ignition coil. |
| Air filter obstruction | When the air filter gets clogged with dirt, the engine can’t obtain enough air to run. | To clean the filter, take it apart. If the filter is damaged, you should get a new one. |
| The Fuel Filter is Clogged | If the gasoline filter is clogged with grime, then the fuel will not flow as freely. | Change out the fuel filter. |
| Damaged gasoline lines | Inadequate fuel delivery to the engine might result from the accumulation of sediment and dirt in the fuel lines. | To clear the gasoline line, blow compressed air through a carburetor cleaner. Fix the line or get a new one if it breaks. |
| Unclean carburetor | The carburetor can get clogged up with deposits of poor fuel and ethanol, cutting off the fuel supply. | The carburetor’s parts should be cleaned. Substitute if broken. |
| Low oil pressure in engine | A Champion generator’s engine is safeguarded by a sensor that prevents operation when oil is too low. | Spread out on a flat surface and fill with oil up to the maximum mark on the oil dipstick. |
| Choke is either set incorrectly or is stuck. | When starting a cold engine, you must turn on the choke to limit airflow. Once the engine is up to temperature, you can turn it off. | Verify that the choke is set properly. If the adjustment is right, make sure the choke linkage is unobstructed and the choke is free to move. |
| Broken recoil starter | If the recoil on your pull start generator is broken or damaged, you won’t be able to use it to start your engine. | See if the recoil can be restrung, and if it can’t, see whether the parts are replaceable. If the recoil mechanism fails, you should replace it. |
| Battery drain, faulty wiring, or dirty connections can all cause electrical failure. | If the battery isn’t fully charged, the generator won’t turn on. | Battery charging, please. If the battery can’t keep its charge, you should get a new one. |
| Electric-starting solenoid failure. | It’s possible for the solenoid to fail due to a weak internal spring or corroded copper plate. | If the solenoid is at fault, it can be determined by skipping it. Replace it if it breaks. |
| The electric starter’s ignition switch is broken. | Champion electric starter models have a defective switch. | The switch must be tested with a multimeter. Until you can have the electric starter fixed, you should use the recoil starter. |
2. Champion Generator Fires Up Before Dying
Many of the same things that prevent a generator from starting might also cause it to shut down after it’s up and running.
In many cases, component problems and fuel constraints can be traced back to just utilizing old gas. It’s possible for it to evaporate, leaving sticky residues in places like the gasoline filter, the carburetor, and the fuel lines.
One possible source of gasoline restriction is a faulty or obstructed fuel tank vent. As the tank’s suction increases, fuel is unable to reach the carburetor. A Champion generator that runs poorly and eventually stops working could have this problem.
Look for sparking sources and obstructions to ventilation as well. A defective ignition coil, dirty spark plugs, a dirty air filter, or a dirty spark arrestor are all examples of things that can prevent an engine from starting.

12 Causes of a Champion Generator’s Untimely Demise
| Cause | Reason for Problem | Solution |
| Dull gas | Aged fuel is less effective, might block the fuel system and even cause engine harm. | Remove all of the old gasoline and replace it with new. Sea Foam is a great fuel addition since it helps clean the fuel system while also stabilizing the fuel. |
| The Fuel Filter is Clogged | If the gasoline filter is clogged, the carburetor won’t get enough fuel. | It’s time to swap out that clogged fuel filter. |
| Air filter obstruction | Clogged with grime and grass, the air filter prevents the engine from functioning properly. | To clean the filter, take it apart. If the filter is damaged, you should get a new one. |
| Fuel line clogging | Inadequate fuel delivery to the engine might result from the accumulation of sediment and dirt in the fuel lines. | To remove the obstruction from the gasoline line, you can use carburetor cleaning in combination with compressed air. |
| Unclean carburetor | Bad fuel and ethanol deposits can cause the carburetor to get dirty and blocked, cutting off fuel supply. | The carburetor’s individual parts should be cleaned. Substitute if broken. |
| Fuel Tank Vent Failure | If the fuel tank vent becomes blocked, the tank will develop a vacuum, severely limiting fuel delivery. | Unclog the fuel tank’s ventilation system. |
| Spark Plug Gunk | A faint spark is all you may get with a dirty spark plug. | Spark plug replacement is required. Check the spark plug wire and the electrode gap to make sure everything is working properly. |
| Ignition Coil Problems | The spark plug will not fire if the ignition coil fails to supply voltage.Perform an ohm test on the starter’s ignition coil. | If you detect a break in continuity, it’s time to replace your ignition coil. |
| Low Oil Pressure in Engine | A Champion generator’s engine is safeguarded by a sensor that prevents operation when oil is too low. | Spread out on a flat surface and fill with oil up to the maximum mark on the oil dipstick. |
3. The Gas Leaks From the Champion Generator
The Champion generator may be emitting a gas odor. Before starting the generator again, the leak must be fixed because the exhaust fumes are harmful.
A generator’s carburetor is a common leak point. The fuel may spill out of the bowl if the carburetor’s bowl gasket fails to seal properly or if the carburetor’s internal parts become stuck.
The fuel filter, fuel lines, and fuel tank should all be checked for leaks in addition to the gas tank and shutoff valve.

Champion Generator Has a Gas Leak (Troubleshoot)
| Reason for Problem | Solution | |
|---|---|---|
| Unclean carburetor | A buildup of chemicals from old gas might clog up the carburetor or wear out the parts inside. | Get the carburetor serviced and any broken components replaced. |
| Dodgy fuel filter | The filter’s plastic casing may eventually deteriorate, resulting in seam leaks. | Change out the fuel filter. |
| Gas tank | A rust hole can form in a metal tank over time. It is possible for a poly tank to leak at the seams. | Substitute the gas tank. In the event that a replacement tank is no longer obtainable, rust holes might be sealed. |
| Gasoline tank shutoff | Leaks are common in both metal and plastic shut-off valves. | Fix the broken valve. |
| Drained gasoline lines | When gas lines dry out and crack, gas leaks. | Fuel lines should be changed. Verify the clamps are properly attaching the fuel line to the fuel components. |
4. Champion Generator is Bogs Down Under Load
If your Champion generator is experiencing power loss while running a load, the problem is likely due to an air or fuel restriction. A possible cause is overloading your generator with too many electrical devices.
| Cause | Reason for Problem | Solution |
| Overloading the System | Plugging in more devices than the generator can handle will lead it to stall out. | Make sure the generator isn’t overloaded. Make sure the total wattage of everything that will be plugged in at once is below the maximum safe level. |
| Bad or stale gas | Over time, fuel deteriorates, increasing the risk that it can clog the fuel system and cause other damage to the vehicle. | Remove all of the old gasoline and replace it with new. Sea Foam is a great fuel addition since it helps clean the fuel system while also stabilizing the fuel. |
| Ineffective fuel filter | If the gasoline filter is clogged, the carburetor won’t get enough fuel. | Remove the gasoline filter and clean it out. |
| Air filter obstruction | If the air filter gets clogged up with dirt and grass, no air can get through. | To clean the filter, take it apart. If the filter is damaged, you should get a new one. |
| Incorrect Choke Position or Frozen Choke | When starting a cold engine, the choke is utilized to limit airflow. If it’s not adjusted properly, the generator won’t get enough air to function. | In order to keep the engine running after it has warmed up, the choke must be in the open position. |
| Spark arrestor with a plug | If debris accumulates on the spark arrestor screen, it will restrict exhaust flow. | Take out the spark arrestor and clean the screen with a solvent and a little metal brush. Repair a broken screen immediately. |
| Unclean carburetor | The carburetor can get clogged up with deposits of poor fuel and ethanol, cutting off the fuel supply. | The carburetor’s individual parts should be cleaned. Substitute if broken. |
