Carb Crust in Float Bowls???, Webber 40ida3c Options

[Mike D.]

I got carb kits just clean and freshen up the webbers on the 6 engine while it is out of the car. Well, when I opened them up I found in one float bowl some crusty yellowish white stuff. I sprayed with some carb cleaner brushed it with a tooth brush wiped it out and blew it with some air and more white crust appeared. What is this and how do I get rid of it? This stuff could obviously clog up jets, which is no good.

I also found that one of the floats is dented, like some PO (IMG:style_emoticons/default/smash.gif) droped it and steped on it, I floats though, should I be concerned about that?


TIA,

I've heard that zinc-body carburetors like Webers and Solexes have a coating that can be (this is the hard part...) permanently damaged by overexposure to carb-dip (principally methylene chloride). could be that what you're seeing is the formation of zinc oxide (that white stuff used in sunscreen...) caused by exposure to the air without this protective coating. (if zinc could rust, which it can it'd be that stuff - rust is iron oxide, and zinc oxide is that stuff...) i don't believe zinc can be anodised so i don't know if another protective coating is possible.

floats need to have a certain volume - if they don't i'd replace it; they should be still available tho ...
