The topic of carburettor cleaning was already discussed in several forums via ultrasound. Even though I had no bad experience with the small “bite cleaners”, which are available for various discounters by about 20 euros, if you disassemble the gasifiers and sound the small parts in them, this is certainly not the yellow of the egg. Also the mixture of vinegar cleaner and hot water used so far brought good cleaning results, but also a redness. In the near future, I would like to add a useful US device, as I always get into the embarrassment of bringing totally dirty carburettors back to front. I would like your help. A cleaning device from Bandelin is with the dimensions 500 x 140 x 100 especially suitable for the insert of a complete carburettor battery. It holds 6 liters of cleaning liquid and has only one hook: It costs 899 euros. (Offer from schalltec) Therefore my questions to the forum: 1. Who has experience with a good ultrasonic device ? 2. How many sounders are the minimum ? 3. Who knows where you can buy a cheap and good device ? 4. What about a far-east product (5 liters content, outlet faucet, heating, 2 sounders) to hold for approx. 200 Euro ? (Such devices are offered again and again via auction, but the sellers usually have nothing to do with the matter, because one buys the cat in the bag) 5. Cleaning liquid (mixture, e.g. Tickopur concentrate with water or only detergent) would you recommend ? I am grateful for every tip, already alone, so that nobody makes fun of my “bite cleaner” Gelle my friend …?
