This is an OEM Zenith rebuild kit for up-draft L63 series carburetors on Wisconsin VH4D and TJD motors. This is a direct replacement for the Wisconsin LQ39 carburetor kit. Note that VH4D motors can have side-draft or up-draft carburetors. This kit is specifically for the up-draft carburetors.
This carburetor kit is NOT for carburetors on the Wisconsin side-draft W41770 and V465D and some VH4D motors. The side-draft carburetors use the LQ37 rebuild kit here.
