Aervoe Carb & Choke Cleaner is a fast acting blend that quickly loosens and dissolves varnish, gum, grease, sludge, and carbon, which may be the cause of hard-starting, rough idling, stalling, engine run-on, high exhaust emissions, gasoline waste and lack of
performance. It is formulated to maximize carburetor performance by cleaning and de-gumming. Not only is it quick and easy to use, it dries fast and leaves no film or residue. Use in any carburetor or fuel-injected gasoline engine. Use on PCV valves, automatic chokes, carburetor components, crankcase breather elements, exhaust gas recycling valves (EGRs) and intake parts.
