Step 1 - The first step is to fully dismantle the carburetor for cleaning. It also allows you to separate the parts that will be painted from those that will retain a natural finish. The corrosion on these float bowls is not uncommon, and can be refinished.

Step 2 - The carb parts to be refinished are given an extended bath in a carburetor cleaner dip can. We soaked ours for about an hour, then rinsed them with cold water to stop the cleaning action, then blew them dry with compressed air, making certain to blow out all internal passages.

Step 3 - Mild corrosion can be removed with a wire wheel on a bench grinder. Just use enough pressure to barely touch the wire wheel. Carb castings are fairly soft and you just want to polish the surface instead of removing metal.

Step 4 - After cleaning off any carb cleaner residue, the parts can be lightly sprayed with carb renewal. It's available in bronze or silver and is resistant to fuel and most fuel additives.

Step 5 - It's easy to see the difference between the unpainted carb parts on the right and the freshly coated float bowl and vacuum canister cover on the left. For less than $10, and an afternoon of cleaning and painting, your vintage carb can look like new.
