Idle adjusting needle with knurled extension - late model
This needle valve is made of stainless steel and has a knurled extension to make adjusting the idle fuel mixture a "no-tool" procedure. It is recommended in any application where access to the idle mixture control on top of the carburetor makes adjusting the idle mixture with a screwdriver difficult.
