What is ultrasonic carburetor cleaning and why is it better than standard cleaning?

Ultrasonic carburetor cleaning uses high-frequency sound waves in a heated solution to remove fuel varnish, corrosion, and debris from internal passages that cannot be reached with manual cleaning. This method restores proper fuel flow and performance far more effectively than spray or hand cleaning.

When should a carburetor be rebuilt instead of just cleaned?

A rebuild is recommended when seals, gaskets, needles, or floats are worn or damaged. If the engine has hard starting, fuel leaks, poor idle, or inconsistent RPMs, rebuilding the carburetor ensures long-term reliability and correct air-fuel mixture.

Do you completely disassemble the carburetor during ultrasonic cleaning?

Yes, we fully disassemble the carburetor before ultrasonic cleaning. All jets, passages, and internal components are cleaned individually, inspected, and measured to ensure factory-correct operation before reassembly.

Can ultrasonic cleaning fix rough idle and hesitation?

In most cases, yes. Rough idle and hesitation are commonly caused by clogged idle circuits or restricted jets. Ultrasonic cleaning removes microscopic deposits that disrupt fuel delivery, restoring smooth idle and throttle response.

Do you replace internal parts during carburetor rebuilding?

Yes, during rebuilding we replace gaskets, O-rings, needles, seats, and worn components using high-quality rebuild kits. This prevents fuel leaks, improves efficiency, and ensures proper tuning after installation.

Do you tune the carburetor after cleaning and rebuilding?

Absolutely. After installation, we fine-tune idle speed, mixture screws, and throttle response to match engine specifications. Proper tuning is critical to achieving smooth operation, fuel efficiency, and engine longevity.

Do you offer this service in Newport Beach and Long Beach marinas?

Yes, we provide ultrasonic carburetor cleaning and rebuilding services in both Newport Beach and Long Beach marinas. We can perform on-site diagnostics and removal, with professional bench cleaning and reinstallation as needed.

Is your engine surging or stalling? Our industrial ultrasonic cleaning bath penetrates deep into microscopic internal passages to remove stubborn ethanol varnish and gum that standard sprays can't reach.

Details

Microscopic Precision

The Science of Clean.
Down to the Micron.

Traditional solvents cannot reach the tiny internal passages of a marine carburetor. We use industrial ultrasonic technology—cavitation bubbles created by high-frequency sound waves—to blast away ethanol gum and varnish from the inside out.

Cavitation Power

Our tanks pulse at 40kHz, creating millions of microscopic vacuum bubbles that implode against the carburetor surface. This energy physically dislodges stubborn varnish from pilot jets that a wire tool can't even touch.

Internal Passage Restoration

Marine carburetors have complex, hidden fuel circuits. Soaking them in a bucket won't work. Ultrasonic waves penetrate solid metal, ensuring the idle and transition circuits flow exactly as the factory intended.

Complete Rebuild

Cleaning is just step one. After the bath, we reassemble your carburetor using premium ethanol-resistant Viton gaskets, new needle valves, and fresh O-rings to prevent future leaks.

The Restoration Process.

From grime to shine.

Strip & Prep

We completely disassemble the carburetor, removing all rubber and plastic components that could be damaged by the heated solution.

Heated Ultrasonic Cycle

The aluminum bodies are submerged in a specialized detergent solution heated to 140°F. They undergo a 30-60 minute cycle of intense cavitation.

Vapor Blasting (Optional)

For heavily corroded exteriors, we can vapor blast the outside to restore the aluminum to a "better-than-new" satin finish.

Bench Testing

Once reassembled, we pressure test the needle and seat (pop-off test) to ensure it holds pressure and won't flood your engine.

Common Questions

Does this fix ethanol issues?

Yes. Ethanol leaves a hard, green/yellow varnish that spray cleaners cannot dissolve. Ultrasonic energy physically shatters this varnish, clearing the blockage permanently.
