Your Generator Quit. Let’s Get It Running.

No fire at all — fuel, spark, air, or a gummed carburetor.

Fires for a few seconds then quits — classic stale-fuel carb clog.

Engine runs but no voltage at the outlets — AVR, capacitor, brushes.

RPM revs up and down — carburetor, governor, or stale fuel.

Takes many pulls before it finally catches — the three usual causes.

Fine in summer, fights you when it’s cold out.

Recoil is stuck, locked, or won’t retract.

Push the button and nothing — battery, solenoid, or switch.

Black, white, or blue — each color means something different.

Bangs on startup or shutdown — timing, fuel, or carb.

Runs fine until you plug something in, then stalls.

Runs then quits hot — load, oil, cooling, or thermal trip.

Shuts off or won’t start with oil present — sensor issue.

Breaker pops the moment a load is connected — overload or fault.

Gas or oil pooling — carb bowl, fuel line, gasket, or overfill.

The #1 cause of no-start and starts-then-dies on stored units.

Reading a plug tells you how the engine runs. Gap, replace, diagnose.

Runs but no power, or wildly wrong voltage at the outlets.

Brushless generators that lose output — cheap part, simple test.

Tank, valve, lines, filter, pump — everything feeding the carb.

Portable + home standby — no-starts and reading fault codes.

EU inverter and EM line — the common fixes.

Dual-fuel and inverter portables — start and run problems.

Harbor Freight 3500 / 5000 / 9500 — the DIY favorite.
