Restore carburetor performance by removing gum, varnish, carbon deposits and dirt build-up. Cleans and frees automatic chokes, carburetor linkage, fuel injection intake systems, manifold heat controls and PCV smog valve. Will not harm oxygen sensors or catalytic converters. Removes Gum, Varnish, Dirt & Carbon


Automatic Chokes: Remove air cleaner, disconnect heat riser tube, mark position and remove choke cover, take out baffle plate. Spray contents on the vacuum piston and cylinder and then on both ends of choke valve shaft. Keep working choke until it becomes free. Start engine and spray the piston and cylinder while working the choke by hand. Replace baffle plate, choke cover, heat riser tube and air cleaner.

Carburetor Linkage: Spray on dirty or oily linkage, let set for a few seconds and flush off by spraying again.

Fuel Injection Intake Systems: Dismantle and/or access fuel injection air fuel intake systems. Spray liberally to instantly dissolve baked on gum, carbon, soil and resin deposits.
