Description
Overview:
The Tappet Adjusting Screw is a genuine Honda component designed to set and maintain correct valve clearance (valve lash) in small petrol engines. Manufactured from durable, hardened steel with a corrosion‐resistant finish, it offers precise thread engagement for accurate adjustment and long service life. This screw helps keep the valve train operating smoothly, supporting easy starting, consistent power and lower mechanical noise. It is suitable for a wide range of Honda engines used on lawnmowers, generators and other compact machinery, including GC135, GC160 and GC190 series. Common applications include popular models such as the EU20i and EU22i generators. As a direct replacement for OEM 90012-333-000, it is a straightforward, like‐for‐like fit when carrying out routine valve clearance maintenance.
