common Honda generator problems-

The generator won’t start

Cause for Honda Generator won’t start-

  • An engine fault, the engine has seized.
  • Oil level is too low in Engine
  • The wrong type of fuel has been used or fuel has been left sitting in the tank for a long time without use
  • Carburetor problem
  • Battery not charged
  • Blockage in the air filter
  • A spark plug is not proper or it is dirty

The generator is not able to generate enough electricity

Possible reason-

  • Overloading disconnect the alternator
  • Any electric defect like- stator motor damaged, short ckt or losing wire connection
  • Capacitor problem

The generator stops after a few seconds


  • Overloading
  • Oil level is too low/high of Engine
  • An electrical defect problem
  • A problem with the capacitor
  • A carburetor problem
  • A problem with the battery or battery requires charging
  • The choke is on
  • An obstruction in the air filter
  • A spark plug is jammed
  • The generator is being used in the wrong environment

Generator power fluctuations

Possible causes-

  • Overloading of generator
  • An electrical fault
  • A problem with the carburetor
  • The choke is turned on
  • Air filter cause
  • The spark plug is clogged
  • The generator is being used in the wrong environment

Fuel leaking in the Generator

The possible reason for this-

  • The gasket is not properly fixed
  • Wear and tear in the fuel pipe
  • Carburetor problem

Smoke coming from the Generator

  • A possible reason for this-
  • The wrong type of fuel has been used
  • The engine oil level is too high or the wrong type of engine oil has been used
  • There’s an oil leak, e.g. the seals on the oil tank are worn
  • The valve guide seal and/or the cylinder bore are worn
  • The piston rings are broken/worn, e.g. oil is leaking in the piston head
  • A problem with the carburetor
  • Carbon has built up in the exhaust muffler

Starter mechanism is not work

A possible reason is-

  • The recoil is broken
  • The engine is seized

Some Honda Generator Problems with Solution

Problem- Honda Generator battery keeps dying

Solution 1- Voltage Regulator

The voltage regulator transfers the exact amount of voltage energy from the alternator to keep the battery charged. If the voltage regulator is bad, the battery will not get enough voltage, which will drain the battery quickly.

Solution 2- Alternator

To determine if the alternator is at fault, use a multimeter to test it for continuity.

Problem- Honda Generator Leaking Gas

Solution 1- Carburetor Gasket

Check all carburetor gasket, carburetor gasket might be dried out or missing.

Solution 2- check Fuel line

Inspect fuel line may be fuel line is cracked. If any fuel line is cracked or dry, replace them.

Solution 3- Fuel tank-

The fuel tank might be cracked or have a small leak. If you find any leak point in the fuel tank, replace the fuel tank.

Solution 4- Primer Blub Test

Primer bulb may be leak condition. Over the season, the rubber of the primer bulb can become breakable and cracked. If the primer bulb is leaking, change it. Do not attempt to patch or repair the primer bulb.

Problem- Honda Generator won’t start

Solution 1-  Check Spark Plug

When the generator won’t start firstly you Inspect the spark plug, use a spark plug tester. if the spark plug is faulty, change the spark plug.

Solution 2- Carburetor

A filled carburetor is usually due to the fuel leaving the generator for a long time. Over time, some of the material in the fuel may evaporate, leaving a thick, viscous substance. This viscous oil can hold the carburetor and block the engine from starting.

Solution 3- Ignition Coil

The ignition coil sends voltage to the spark plug when the engine is running. If the ignition coil is faulty, the engine cannot start. Before replacing the ignition coil, make sure that the spark plug is working properly. Test the ignition coil with the help of ignition coil tester. If it is in a faulty stage, replace the ignition coil.

Solution 4- Recoil Starter testing

The recoil starter parts engage the crankshaft to turn the engine. If this starter assembly is faulty, it may not attach the crankshaft correctly. Remove the starter assembly and inspect to determine if it is working properly. When you pull the starter rope, the tabs and cams protruding from the pulley should hold the hub on the engine, causing the engine to turn. When you release the rope, the tab should retract and bring the rope back to the pulley.

Solution 5- Start Switch

The problem of the generator, not starting can also be caused by the fault of the start switch. To determine that the start switch is faulty, use a multimeter to test it for continuity. The switch must have an open contact in the ‘off’ position and a closed contact in the ‘on’ position.

Problem- Generator Won’t Stay Running Condition

Solution 1- Carburetor

If the old fuel was left in the engine for a long time, some of the volatile ingredients could evaporate, leaving a thick, viscous product that could create problems in the carburetor. The solution is to clean the carburetor with the help of a carburetor cleaner. If it is not effective, replace the entire carburetor.

Solution 2- Inspect the fuel cap

If the fuel cap vent is full, the air will not enter the tank and it stops the flow of fuel to the carburetor causing the engine to stall. If sometimes the fuel cap vent is full, loosen the cap slightly and then try to start the engine. If loosening the fuel cap keeps the engine running it is potentially full and has to be replaced.
