How to Polish a Demon Carb

Polishing Demon carburetors is not a particularly labor-intensive process.

Demon carburetors come from the factory equipped with a basic, lightly polished finish that is acceptable for most applications. Polishing your Demon carburetor to a mirror shine, however, can be accomplished with just a few hours' worth of work and a rotary tool. Mirror shines on your carb can improve the look of show-quality vehicles, though they don't improve the performance of the car and will eventually tarnish, meaning that you'll have to keep polishing your shine after you've polished it once.

Remove the air cleaner from the carburetor of the vehicle to access the Demon carb. This may be done by removing a wingnut from the lid and then lifting the base off the carb, or by unscrewing a plastic intake from the carburetor with a screwdriver.

2

Mask off the parts of the carburetor that you do not want to get polishing compound into or on. You can use painter's masking tape for this purpose. You will want to cover the large, round intake of the Demon carburetor, as well as the fuel and vacuum lines that run to it. In addition, remove the throttle linkage on the side of the carburetor to get it out of the way --- the throttle linkage is a small, thin wire attached to the side of the carburetor that actuates the valve inside.

3

Insert the polishing wheel shaft into the rotary tool's chuck and tighten it down. Set the rotary tool's power to its lowest setting, to avoid damaging the polishing wheel, then apply the polishing compound to the wheel, letting the compound stick melt into the fabric of the wheel.

4

Polish the surface of the carburetor with the polishing wheel, beginning with the sides of the unit and working around and over the bumps in the cast metal. Since Demon carburetors are mostly polished already, imparting a mirror shine to the zinc surfaces won't take long, and should only require the use of only one type of polishing compound.

5

Wipe away the excess polishing compound from the carburetor with a clean rag, using it also to buff the newly shined surfaces to a high-gloss luster.

Tips & Warnings

Cover the intake and outlet of the carburetor with masking tape or duct tape to prevent polishing material from entering the jets if you remove the carb from the engine before polishing.
