scaly residue in carb after cleaning?

Just picked up this bitchin' General 5 star with a stock minarelli V1 and dellorto 14.12 carb. Teaching myself the ins-and-outs of all things mechanical, and since it's the smallest, I thought I'd take on the carb first. Issue is (or is it?) that, after a thorough spraying with Gumout carb cleaner and then brake cleaner (after I dried and wiped it down), I swear there's more weird residue in and on the old thing than there was to begin with. Wondering if anyone can tell me if this is normal, or if I should go about another way of cleaning this up? Just want it squeaky clean before I install it again

All right most people don't know this but those tankers that carry the gas in bulk all have three grades of gas in them and when they wash out the trucks they use lime some of it gets dissolved in the gas in the next batch what happens is when ethanol gets involved it holds it in suspension and when it settles out you'll get this white crummy stuff that just fills the carb it's a crystalline growth that there is the start of it the best way to clean that crappy metal is the strongest vinegar you can find usually that would be 7% you leave it in there overnight if you have one of them ultrasonic vibrator things all the better after 24 hours wash it out with warm water and a little baking soda then rinse dry blow out with compressed air

Thanks @thewhitedog! I'll give it a try

Re: scaly residue in carb after cleaning?

vinegar will eat through pot metal ,if your carb is such so keep a eye on it,I had it eat through a petcock.

Why would they wash out a petroleum tanker? To haul milk in it?

Re: scaly residue in carb after cleaning?

Nope, milk is a whole different tank, single chamber, which doesnt help with the slosh unlike oil tankers which are multi chambered to prevent it.

Milk tankers are sanitized with extremely hot water after every load and sealed with seals that have matching serial numbers, if the load has mis matched serial numbers it is rejected and a 15k truck load will only be worth about 3k.

I work in the milk industry.

Some tanks are even blessed by Rabbis so they can be Kosher! Imagine that!

I remember reading about some cases of salmonella poisoning from tankers that were not cleansed from hauling some other dairy product (iirc liquid egg) before milk was loaded into them.

I was in logistics so basically yeah they have to wash them out every now and then no matter what they carry

Re: scaly residue in carb after cleaning?

Yeah when you cleaned out the petcock did you remember to deactivate the acid with baking soda?

Re: scaly residue in carb after cleaning?

Update here: carb was definitely made out of pot metal, so there was some erosion throughout -- not enough to lose sleep over, however. Threw some baking soda on and it cleaned up real pretty-like. If any sleep was lost, it was entirely due to excitement: reassembled the carb and tacked it onto the manifold Saturday and got the General running for the first time in two weeks. Feeling pretty good for a shitty little pencil-pusher like myself. Thanks for the help guys.

Go to the grocery store and get a dozen lemons and squeeze the juice into a container! Or purchase a carton of concentrate lemon juice
