Rebuilding a wrecked carburetor

[MonsTT]

Hi guys,
Iv'e just treated myself with a "new" TT600s & i'm thrilled to get it running again (already have two running machines), the bike was stored for about 10 years, its mechanical status should be ok, engine seems to move freely.
Starting with the carburetor, I found the worse pile of $#@* i ever seen, it was packed with white thick coating, concrete to the touch, which i assume was fuel back in the day.
I already managed to remove 80% of it by using hours of ultrasonic cleaner and several different carb cleaners, however, the last layer seemed like it been merged into the aluminum body.
To all of you who experienced with restoration, any ideas ?

I love a challenge but i fear those are toast, keep the parts that are good but bin the rest.

Bad fuel is brown, that looks more like water damage, aluminium oxide (corrosion) that's why it's eaten into the body.

But why only on the inside?

An attempt at converting to HHO perhaps

i'm pretty sure it is fuel, I could see the same white deposit within the head fuel passageways, with a shape of little droplets on the side wall- fuel spray

I'd guess water in fuel while in use, or some other corrosive contaminant. Last post over a year ago, how did it pan out?
