How to Quickly Clean Personal Watercraft Carburetors

A benchtop ultrasonic cleaner is a wise investment for operators of personal watercraft sales and service organizations to quickly and thoroughly clean carburetors and remove gum deposits caused by storage without adding a gasoline stabilizer to the fuel in the tank.

Sonic action in an ultrasonic cleaner is far superior to manually scrubbing and soaking in a wash tank or using fume generating aerosol sprays. Cleaning jet ski carbs is also faster because dismantling is reduced to a minimum. The modest investment required will be quickly repaid due to increased throughput and superior results; disposal concerns are reduced because the cleaning solution is biodegradable.

Ultrasonic cleaners are offered in a wide range of sizes and features. An example for a small-to-medium sized marine equipment service organization or a water jet ski club is the 40 kHz, .75 gallon capacity TOV120-3L available from iUltrasonic. This compact unit has a thermostatically adjustable heater to improve cleaning effectiveness when removing grease, oils and gum from complex carburetor parts, and a timer to let you set it and forget it while it does its job. It is shipped with a lid to reduce noise and solution evaporation, and a basket to support carburetors and other small parts at the proper depth.

A Cleaning Cycle for Jet Ski Carbs

Here’s the good news about ultrasonic cleaning vs. manual cleaning. As hinted above, you do not need to totally disassemble carburetors because sonic cleaning action reaches all surfaces immersed in the ultrasonic cleaning solution. We do recommend allowing the solution to access the float. Scrubbing occurs when imploding cavitation bubbles blast away all contaminants without damaging rubber gaskets and other non-metallic components.

First prepare the cleaning solution. We suggest biodegradable elma tec clean A4 universal ultrasonic degreaser formulated for engine parts such as carbs, gears, bearings and fuel injectors. Recommended dilution is to 1 to 5% with water depending on the condition of the parts. Fill the cleaner tank half full with water then add the correct amount of elma tec clean A4. Add more water to the tank fill line.

Turn on the ultrasound and allow the solution to degas for about 10 minutes.  This drives off trapped air which otherwise slows sonic cleaning action.

When you are ready to clean set the thermostat to 70?C.   While the liquid is heating place the carb into the basket, then lower the basket into the solution and cover the tank.  Set the timer for 20 minutes. Actual cleaning time depends on the condition of the parts.

At the end of the cycle remove the carb and inspect.  If satisfied use fresh water to rinse away traces of the cleaning solution.  Parts should be dried before reinstallation.

A maintenance tip: Skim off residues that rise to the surface and set them aside.  When the cleaning solution becomes discolored and cleaning time takes longer the solution should be replaced. Drain the tank and dispose of the solution and skimmed residues according to local regulations. Clean the tank according to the manufacturer’s recommendations before refilling it with fresh solution. Don’t forget the degas step.
