Carburetor Cleaner

Engine

Dissolves stubborn varnish and carbon deposits in carburetors and fuel passages to restore proper fuel atomization and engine idle quality.

Carburetor cleaner is a heavy-duty solvent designed to remove built-up varnish, carbon, and gum from carburetor passages, jets, and associated fuel system parts on older or vintage vehicles. It restores fuel flow and proper fuel atomization when a carburetor becomes clogged or sluggish from sitting or contaminated fuel. This cleaner is applied by spray or soak and evaporates completely without leaving residue.
