White deposits in carbs from Ultra Sonic cleaner

(1/8) > >>

Nurse Julie:
Hi All.
Just picked up my carbs from the cleaners. Cleaned in a big ultra sonic cleaner with some carb cleaner added. On the whole the carbs look alot cleaner generally but I seem to have what looks like Calcium deposits in some areas. Mainly where the choke flaps are and on the flaps. Also some very small areas of white stuff in some of the outer body nooks and crannies. Now, it seems easy to remove the stuff on the outside but what do I do about the rest and how do I know the internals are not full of this crud as well?. I had removed and will be replacing with new, all the jets that usually hang down in to the bowls so they won't be a problem, but what about everything else inside ?. Should I take the carbs apart from the top as well and check everything ?.Apologies if my explanation's are not too good.
Ta in advance
Julie

That's a bugger- but to be honest- air makes carbs oxidise- that what happens to bare ally. Ive never had carbs cleaned by an ultra sonic process but some folks speak highly of it. Im too tight or cant be arsed- mixture of both. I suffer carb cleaner and an airline. Id clean the obvious off with a toothbrush and some wd40 and fit then/fire it up.

Funny .. Five minutes ago  I have just put a carb. body from a CB750,  that I am giving to elBurro on here,  into the US cleaner with some new additive I just got from Allendale electronics that is supposed to be suitable for carbs and non- ferrous in general. They are in there at 55°C with the solution (they recommend a 10% solution at 50 ->60 °C. It's a big industrial US cleaner and will give you an appraisal in a couple of hours. The carb body has  the white oxide on the inside, as you describe Julie.
