When severe weather strikes and power goes out, your generator becomes your lifeline for keeping food fresh, maintaining heat or cooling and powering essential devices. But a generator that's been sitting unused won't reliably start when you need it most. Preparing your generator before storm season arrives means checking and replacing critical parts that ensure reliable operation during emergencies.

Start with the Spark Plug

A fouled or corroded spark plug is the most common reason generators fail to start after storage. Remove the spark plug and inspect it for carbon buildup, electrode wear or corrosion. If the porcelain is cracked or the gap looks incorrect, replacement is necessary. Fresh spark plugs ensure reliable ignition, especially after months of storage. Replace spark plugs annually before storm season for peace of mind.

Air Filter Inspection and Replacement

Clogged air filters restrict airflow and prevent proper engine operation. Remove the air filter and hold it up to light, if you can't see through it clearly, it needs replacement. Dirty filters cause hard starting, rough running, and reduced power output exactly when you need maximum performance. Paper filters should be replaced rather than cleaned for optimal results.

Battery Check for Electric Start Models

Electric start generators rely on batteries that lose charge during storage. Test battery voltage and charge fully before storm season. Corroded terminals prevent reliable starting, clean terminals thoroughly or replace severely corroded batteries. A dead battery means manual pull-starting during an emergency, which can be difficult or impossible depending on generator size.

Inspect Fuel Lines and Filters

Cracked or brittle fuel lines leak and prevent proper fuel flow. Squeeze fuel lines checking for cracks or soft spots indicating deterioration. Replace questionable fuel lines before they fail. Fuel filters trap debris and should be replaced annually to prevent carburetor clogging.

Test Run Before You Need It

After replacing parts and performing maintenance, run your generator under load for 30 minutes. This test confirms everything works properly and identifies problems while you still have time to address them. Waiting until the storm hits to discover issues leaves you without backup power.

Don't Wait for the Storm

Generator preparation takes less than an hour but provides priceless peace of mind during emergencies. Stock critical replacement parts now while stores are open and shipping is reliable. When severe weather threatens, you'll have confidence your generator will perform exactly when your family needs it most.
