Carb & manifold cleaning + Bead Blasting = Easy
Posted 22 November 2009 - 10:35 AM
I've tried a few weak chemical cleaners and autosol etc but nothing really removed the stains. After I excepted that some of the throttle shafts were bent and would require dissassembly, i gave them a hit with beads.
The blasted carb next to the others on the manifold, which I did hit with beads in a few small sections to see how they would work.
One question I do have now is should I coat the new surface in a sealer? I have a small spray can of automotive paint clear, would that work or is there a better metal sealer/cear coat I should use?

But I think WR-Us is on to something with the football pump tip, does it give you a more controlled localised area when directing the soda?
This set up looks like it would have way too much flow.

Pics so i can copy your ideas thanks
anyway, depeding on what finish you want on the carbs will give you an idea what to do with them.
If you wanted them shiny, you'd need to sand them down, then polish them (an electric toothbrush is handy for getting into difficult spots)
If you want to keep the standard cast alloy look, get them as clean as you can.
Its also a good time to smooth off any casting marks, if they are obvious.
There is a real nice VHT paint, that is a high temp non gloss cast alloy finish.
Put a few coats of that over it, and they'll never dull off.
They are also easier to keep clean.
The real trick is attention to detail, if you make sure you dissasemble everything when you do it, you wont have screw heads and plugs painted over.
If you want to keed the raw alloy finish with no paint you'll just need to clean it off more often.
Whatever you do though, dont clear over the raw alloy.
It'll go yellow and flake off over time, and its a MASSIVE pain in the ass to get it all off.

FWIW, about 3 years ago I had my manifold and triple webers glass bead blasted and I then coated them with Glisten PC which is one of the PPC products (the makers of POR15). I am more than happy with the result, there is no yellowing and any petrol stains can be easily removed with a spray of carb cleaner. I am going to use the same stuff on the polished alloy wheels of a classic motorcycle I am restoring. See link

Sounds like the same type of coating used on new OEM alloy wheels, any chance of a pic of your weber / manifold set up?
