Noticing your generator’s a bit sluggish lately? Chances are, the carburetor’s gunked up. Giving that carb a good cleaning can boost performance big time and add years to your generator’s life. Stick around, and I’ll walk you through how to get it purring like new again.

Why bother cleaning that carburetor?

The carburetor’s basically the heart of your generator’s engine, mixing up air and fuel. Over time, gunk like dirt and residue builds up and clogs things, causing the engine to run rough, making it hard to start, and burning more fuel than it should. Keeping it clean means your generator runs smooth, especially when you’re counting on it.

Get ready to clean

Safety is number one

• • Kill the power: Make sure the generator’s switched off and unplugged from everything.

• • Let it chill: Give the engine time to cool down so you don’t burn yourself or have any nasty surprises.

• • Gather your gear: Grab screwdrivers, wrenches, carb cleaner, some compressed air, a little brush, clean rags, and don’t forget your gloves.

Watch out for fuel

• • Empty the tank: Put a container under the carburetor and drain out the fuel. Be sure to get rid of it the right way, according to your local rules.

• • Clean up spills ASAP: If you splash any fuel, wipe it up right away to avoid any mishaps.

Disassemble the carburetor

Find and remove the carb

• • Spot the carburetor: It’s usually hanging out next to the air filter. If you’re not sure, flip through your generator’s manual. Can’t find your model number? We’ve got a handy guide to help you out.

• • Take off the covers: Remove any shields or covers that are in the way.

• • Disconnect everything: Carefully unhook the fuel lines, throttle linkages, and any other bits connected to the carb.

Take it apart carefully

• • Keep track: As you pull things apart, snap pics or jot down notes so you know how to put it back together.

• • Gather tiny pieces: Remove jets, screws, needles, and stash them somewhere safe where they won’t roll away.

• • Keep it clean: Cover any open ports and the manifold with a clean rag to block out dirt and junk.

Clean the carburetor components

Start cleaning

• • Soak the metal bits: Drop the metal parts into some carb cleaner solution. Check the instructions for how long to leave them soaking.

• • Optional ultrasonic cleaning: If you’ve got an ultrasonic cleaner handy, it can really get into those tiny nooks and crannies to blast away stubborn grime.

• • Scrub away: Use a small brush to gently scrub off any remaining crud.

Clear out jets and passages

• • Blast with air: Use some compressed air to blow through all the holes, getting rid of leftover cleaner and bits of gunk.

• • Unclog the jets: Gently poke a thin wire or small drill bit through the jets to clear any clogs. Don’t force it—you don’t want to damage anything.

• • Check everything twice: Make sure all the fuel and air passages are clear as day for the best performance.

Reassemble the carburetor

Dry and check the parts

• • Dry them off: Wipe everything down with a clean rag and let the parts air dry completely so there’s no moisture hanging around.

• • Look over for damage: Check for any worn-out or busted parts that might need replacing.

Piece it back together

• • Use your notes: Refer back to your photos or notes to make sure you’re putting everything back in the right place.

• • Line it up right: Make sure all the parts, like gaskets and washers, are lined up properly.

• • Tighten it up: Screw everything back in securely, but don’t go crazy and over-tighten—you don’t want to strip any threads or break something.

Test the generator

Before you start

• • Hook up the fuel lines: Make sure all the connections are tight and there’s no fuel leaking out.

• • Fill ‘er up: Pour in some fresh gas. If you can, use ethanol-free fuel to keep the carb happier longer.

Start it up and see how it goes

• • Crank it up: Fire up the generator according to the manual.

• • Keep an ear out: Listen to how the engine runs. It should hum along smoothly without any coughing or stalling.

• • Look for leaks: Check around the carb for any fuel leaks.

• • Put it to the test: Plug something in to make sure the generator’s giving steady power.

Extra tips to keep in mind

Keep up the maintenance

• • Clean it regularly: Give the carb a cleaning now and then, especially if you’re running the generator in dusty places.

• • Go for good fuel: Use top-notch, ethanol-free gas to help prevent corrosion and crud buildup.

• • Add stabilizer: If the generator’s gonna sit around for a while, toss in some fuel stabilizer to keep the gas fresh.

When you store it

• • Drain the fuel: Empty out the fuel tank and carb to stop gum and varnish from forming.

• • Keep it dry: Store your generator somewhere dry to avoid any moisture problems.
