I would offer to do them for you but for the fact that my US cleaner (600watts) blew up and took out my electrics in the garage. It cost me £400 to have a new consumer box and the garage rewired!
The best cleaning fluid to use in a US cleaner is' US-CAR' available from R&D Laboratories Ltd (www.mistralie.co.uk) I can guarantee from experience good results using this product.
Here's another one I did earlier :D

Thanks John. I will not despair, worse things will happen I'm sure :)

Well the carb still had deposits after immersion in cleaning fluid at 55 deg C in the US bath below. Think US cleaners are OK for gummed up carbs and getting to internal drillings etc. but not so sure about carbs that get acid rain inside them, when left outside, which causes corrosion to the zinc based alloy (white deposit possibly zinc carbonate). One thing to be careful of is that you can get black smutty deposits if you use the wrong cleaning fluid and you lose that nice blue sheen that the surfaces originally had.
I will have another go tomorrow, as the cleaner would only go to ten minutes at a time (need to find manual to set for longer) . I had it on sweep & high boost burst so don't think it's anything to do with the US machine
Here is the fluid I used diluted 1 part to 10 de-ionised water at 55 deg C ( as per instructions)

Here is the machine I am using:-

Ash, that looks a big & useful cleaner. Mine was small & useless.. my fault for not researching it enough.
I too have had that powdery effect when cleaning... thought "warnings labels are for wasters" & applied oven cleaner to my 400's hubs. (on the bench). 30 mins later removed it & found a cleanish but oxidised finish which had actually taken away the finish. £40 to get it polished - dang. (But it looks fantastic now)
Ya live & learn....

Ash, that is bigger than mine ;D
