These are Carburetor Master Rebuild Kits for the Carter YS Carburetor used on the Willys M38 Military Jeep. This Master Rebuild Kit is the best kit available today of its kind. No other kit offered by other dealers can compare. This kit contains a new mixture screw and many other pieces that these other so called master kits lack. This is a true master rebuild kit.

This Kit is ONLY for the M38.  DO NOT purchase this kit if you intend to use it on an M38A1.
