Carburettor Cleaner STH177

STH177 is a special highly active cleaning agent for the intake and exhaust systems, throttle valves and carburettors. It excellently removes contaminants and deposits. Contains solvents that easily remove oil, rubber, resin, grease, and old coatings. Improves fuel flow, increases engine performance, reduces consumption, and optimizes carburettor performance. STH177 has excellent cleaning abilities due to a special surface activity. 177 features a special 360° rotating valve that allows application even on hard-to-reach places turned upside down. The product is also suitable for catalytic converters.
Spray the treated areas of throttle valves and carburettors and let it work for 2-3 minutes with the engine off. Then, with the engine running, spray the agent into the intake and throttle valve for about 30 seconds and slowly increase the rpm to completely burn off all residues.
