W7042 is a professional-grade, multipurpose solvent engineered to eliminate the most stubborn deposits from carburetors, throttle valves, and injectors. Designed for deep cleaning without the need for component disassembly, it effectively restores engine performance by stripping away resins, tars, and grease.

Performance Properties

• Deep Penetration: Rapidly reaches internal channels and moving parts.

• Zero Residue: Evaporates quickly, leaving treated metal surfaces perfectly bare and clean.

   

• Contaminant Removal: Dissolves oil, grease, resin, and tar-type carbon build-up.

   

• Plastic Safe (PA66): Formulated to be neutral toward PA66 nylon, making it safer for specific engine components.

   

Technical Specifications

Application Guide

Suitable for: Carburetor inner/outer surfaces, throttle valves, injectors, and all heavily soiled bare metal surfaces.

Instructions for Use:

1. Preparation: Remove the air filter and shake the can thoroughly.

    

2. Start Engine: Idle the engine. Ensure no dust or debris enters the intake while the filter is removed.

3. Cleaning: Maintain high engine speed (throttle lever) and direct the jet onto valves, walls, and channels.

    

4. Throttle Action: Periodically press the accelerator while spraying to prevent the engine from stalling.

5. Post-Clean: The engine may temporarily smoke or start poorly as loosened sediments burn off. Performance will normalize after several throttle pumps.

⚠️ Material Compatibility Warning

This is a highly potent solvent. Observe the following precautions:

• Dissolves: Most plastics, rubber, and automotive paint.

   

• Avoid: Do not use on engines equipped with Oxygen Sensors or Catalytic Converters.

• Surface Check: Ensure the solvent does not come into contact with lacquered or painted exterior surfaces.
