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,

So why in god's name was this material chosen for making carbs?

as opposed to what ?

it's cheap, easy to mold into complex shapes, easy to machine, doesn't rust, and properly treated, doesn't corrode.

brass and bronze are expensive and heavy. aluminum and magnesium are possibilities, but i bet there's some of each of those in the 'pot metal' that makes up a carburetor body.

i'm sure contemporary fuels full of oxygen-bearing additives are doing the coatings and base metals no good.

treat 'em right and they'll do a good job for a long time. it's hard to get car makers excited about the problems, of course, because they want to sell you a new car. Porsche hasn't made a carbureted car since - what - early '73 ? (911T with Zeniths...)

i wonder what PMO is using as their carb body material these days - and what it's coated with ... certainly they're priced like they're cast platinum ...
