Ultrasonic Cleaning

Ultrasonic cleaning is the process of complete removal of a wide variety of contaminants from objects including carburetors by high frequency sound waves. These non-audible sound waves create a scrubbing brush action to effectively remove scale from carburetors. Contaminant removal includes stale fuel residue, unleaded petrol deposits, sediments, grease and many other unwanted substances.

It is non caustic and non-abrasive so is very popular for internal cleaning of carbs, jets, ect. Ultrasonic cleaning uses cavitation bubbles induced by high frequency pressure (soundwaves) to agitate a liquid which provides an effective cleaning method.

No harsh chemicals are used, only a specifically designed detergent to help breakdown the years of grime that has built up over the years.

Most problems we see with carburettors are down to the dirt and grime or blocked passage ways. It provides a powerful yet gentle cleaning process for all hard to reach areas, What it wont do is remove staining and general dulling of aluminium.

At Second City Customs we offer a full Carburettor Ultrasonic Cleaning and Overhaul Service in the West Midlands.

This service is available for most Amal, Keihin, Bendix, Linkert, Hitachi, S&S, Mikuni, Dellorto, Zenith and SU Carburettors. We wash your carburettor(s) to remove all external residue.

Multiple carburettor banks are disassembled to individual carburettors. Each unit is fully dismantled (CV and other butterfly throttle carbs' throttle shafts are left in place). All parts are cleaned in our Temperature Controlled Ultrasonic Tank using a De-ionised Water and Carburettor Specific Detergent Solution, rinsed and air dried. All parts are then inspected. Only then if any part requires replacement is it then replaced. Each carburettor is then reassembled.

Multiple carburettor banks are assembled, linkages lubricated and the throttles visually synchronised.

Rebuild / Service Kits (seals, diaphragms, slides, gaskets), replacements for worn or damaged parts and fasteners are subject to additional parts charge.

Mail order return service available for those from further afield.
