This is an OEM Zenith carburetor rebuild kit for side-draft L57 and L77 series carburetors on Wisconsin VH4D, W4-1770, and V465D motors. This is a direct replacement for the Wisconsin LQ37 carburetor kit. Note that VH4D motors can have side-draft or down-draft carburetors. This kit is specifically for the side-draft carburetors.
This carburetor kit is NOT for carburetors on the Wisconsin down-draft L63 series carburetors on TJD motors and on some VH4D motors. The up-draft carburetors use the LQ39 rebuild kit here.
