Husqvarna Generator won't stay running: Common Causes & How to Fix
1 Husqvarna Generator Carburetor
Most Common Solution
Repair Instructions:
Your carburetor could be blocked. This often happens when fuel stays in the Husqvarna generator for a long while. As time goes by, parts of the fuel can disappear and leave a sticky, thicker material behind. This sticky material can block the carburetor and stop the engine from starting. If your carburetor is blocked, try using a carburetor cleaning product. If it still doesn't work well after cleaning, you might need to rebuild or replace the whole carburetor.

3 Husqvarna Generator Fuel Cap
Common Solution
Repair Instructions:
When the engine uses fuel, the amount in the tank goes down. To balance this, the fuel cap has a tiny hole, or vent, to let air in. But if the vent gets blocked, air can't enter, creating a vacuum or "vapor lock". This stops fuel from getting to the carburetor, causing the engine to stop. To see if the cap's vent is blocked, try loosening the cap a bit before starting the engine. If the engine keeps running with the cap loose, the vent is likely blocked and you'll need a new fuel cap.

- Turn fuel valve to ""OFF"" position to prevent fuel from leaking.

- Check that new fuel cap gasket is in good condition. Replace if worn or damaged.
- Install new fuel cap by screwing it clockwise into fuel tank opening.
- Tighten new fuel cap securely until snug. Do not over-tighten.
- Turn the fuel valve to ""ON"" position once the new cap is installed.
- Check for fuel leaks around the new fuel cap by tipping the Husqvarna generator on its side.
