Clean lawn mower carburettor

Ultrasonic cleaner for cleaning carburettors from garden tools such as lawnmowers.

In carburettors of garden tools such as lawnmowers, deposits settle in the channels and nozzles of the carburettor system after a long period of operation. Especially after a long period of non-use in winter storage, the volatile components of the fuel escape and lead to deposits of the less volatile substances in the petrol. In 2-stroke combustion engines, components of the oil mixture are deposited in the carburettor and lead to starting problems or insufficient combustion in the engine.

For thorough cleaning of the carburettor, it must be removed from the engine. To do this, first dismantle the air duct or air filter and the fuel line. Then the carburettor can be detached from the engine block by removing the flange screws.

Conventional cleaning methods such as brushing with brake cleaner or soaking in petrol/brake cleaner mixture do not adequately clean off the contamination in the inaccessible places on the carburettor mechanics and in the fuel lines.

With ultrasonic cleaning, deposits on the carburettor nozzles can be gently removed. The finest cavitation bubbles clean the carburettor even in hard-to-reach places. It is important during ultrasonic cleaning that the float housing is dismantled and that the bath fluid reaches all areas of the carburettor to be cleaned. After ultrasonic cleaning, the carburettor regains its original performance. This is particularly noticeable in the improved starting behaviour of the corresponding engines.

For the ultrasonic cleaning of carburettors, BANDELIN offers a complete solution that has proven itself with many users, e.g. in the automotive sector or for cleaning motorbike carburettors. The disassembled carburettors are put into a SONOREX SUPER ultrasonic bath with the biodegradable cleaning concentrate TICKOPUR R 33 for a few minutes at 50 - 60 °C and the dirt deposits are gently removed in an environmentally friendly way. The ultrasound creates microscopically small bubbles which, when they implode, gently remove the dirt even from hard-to-reach places.

After cleaning in the ultrasonic bath, the carburettor is rinsed under running tap water and gently dried, e.g. with compressed air or a soft cloth. The cleaned carburettor can then be reassembled and fitted to the engine.

This gentle cleaning method significantly improves the operating behaviour of the engine, saving time and costs. Ultrasonic baths in various sizes as well as a wide range of accessories are available for a high cleaning volume.

In addition to cleaning carburettors, the ultrasonic unit can also be used for many other cleaning applications in the workshop. This includes the cleaning of spark plugs, Injectors, filters, fittings, screws and many more.
