Ultrasonic cleaners solve problems\u00a0<\/strong><\/h2>\n

\"Ultrasonic<\/p>\n

Every once in a while, I run into a carburetor that won’t work properly no matter how much time I spend on it with solvents, compressed air, and small-diameter wire.<\/p>\n

The solution to this problem is to clean all of the parts, including the carburetor body, in an ultrasonic cleaner.<\/p>\n

How does it work?<\/strong><\/h3>\n

Ultrasonic cleaners work by sending high-frequency sound waves through a tank\u00a0of solution. The sound waves cause a process called cavitation to occur in the solution.<\/p>\n

When cavitation occurs, tiny bubbles\u00a0implode\u00a0<\/em>against the surfaces that need to be cleaned.<\/p>\n

\"Dirt<\/p>\n

Ultrasonic cleaners work really well on carburetors.<\/p>\n

They also work well on transmission parts, engine parts, basically anything that will fit in the tank. The tank on my cleaner measures 12″ x 9″ x 6″, which is large enough for most single carburetors and even racks of four carburetors, if I un-gang them first.<\/p>\n

\"Trans<\/p>\n

Four racks of carburetors may also be cleaned one half at a time, if left assembled.<\/p>\n

Testing the ultrasonic cleaner<\/strong><\/h3>\n

A good way to test a new ultrasonic cleaner is to drop a piece of aluminum foil in it for 5 minutes.<\/p>\n

The imploding bubbles of cavitation (horrible name for a band) should perforate and tear the tin foil.<\/p>\n

I did the test on my cleaner, and this is how the tin foil turned out:<\/p>\n

\"Ultrasonic<\/p>\n

Before and after, the results of using an ultrasonic cleaner<\/strong><\/h3>\n

It is not uncommon to have a carburetor that by all accounts seems clean, has clean jets, even looks clean on its visible surfaces, but fails to\u00a0result in a good-running bike after installation.<\/p>\n

\"Dirt<\/p>\n

After 30 minutes in an\u00a0ultrasonic cleaner, that same carburetor results in a perfectly running bike that responds to minute adjustments of its idle and mixture screws.<\/p>\n
