Carburettor Cleaning & Refurbishment - Harper's Ultrasonic
Ultrasonic Cleaning is not a miracle cure or magic, but it still represents the best way to clean intricate or hidden areas of components. Here are some of the most common questions we get asked about ultrasonic cleaning:-
Q. Will ultrasonic cleaning make my worn components like new?
A. No, ultrasonic cleaning can only remove dirt, fuel varnish, gum etc, it cannot replace material that has been worn or corroded away.
Q. Does ultrasonic cleaning damage components?
A. In many years of experience we have yet to see any damage result from this cleaning technique.
Q. Can ultrasonic cleaning remove corrosion?
A. some corrosion can be removed with special solutions designed specifically for this purpose, however, heavy corrosion may not be completely removed.
Q. Is ultrasonic cleaning safe for use on painted components?
A. Painted components can be cleaned with care, but temperature and time need to be limited as poor quality or degraded paint will be almost completely stripped if care is not taken. In general, lacquer on polished components will normally not withstand the cleaning process and a high temperature clean for as little as half an hour can completely remove factory finishes from polished alloy components
Q.Can ultrasonic cleaning remove a broken mixture screw tip from my carburettor?
A. This can sometimes work, but we offer no promises
Q. Why do you recommend careful inspection and replacement of Keihin FCR float valve assemblies?
A. As Keihin FCRs do not have a float bowl overflow facility it can be possible for fuel flowing past a defective float valve to flood the engine whilst not running, this can lead to hydraulic lock in the engine and bent connecting rods.
Q. what other items can you clean?
A. We are happy to quote for horological, antique firearms, antique or modern locks (such as Abloy Disc Detainer Cylinders) and many other mechanical items that require comprehensive yet gentle cleaning without complete disassembly.
