The synthetic aerosol formula quickly and efficiently dissolves and washes off carbon deposits from air flaps and throttles, walls of the mixing chambers and channels of the carburetor. It removes soot from the inlet valves and bottom of the pistons. It helps restore factory parameters of the carburetor without disassembly. It makes carburetor alignment easier in order to get the minimum emission toxicity level and gasoline consumption. During repair works (with partial carburetor disassembly), it ensures efficient cleaning of the idle run system, the solenoid valve of the override-idle economy device, the air and fuel nozzles, the float chamber, the shut-off needle valve, the economizer. It is recommended for annual application, additionally — before the maintenance check, in case of medium-quality gasoline use — each 5000 - 7000 km. The formula is safe for catalytic convertors of all types. It comprises the synthetic metal conditioner SMT2, protecting the throttle axle, shut-off valve of the float chamber of the carburetor and guide bushes of valves from wear. It prevents ferrocene formation on spark plugs and extends their service life.
