does the kit come with the "gauge" to set the bowl to 3/8?

Willys Jeep Parts Tech:
Sorry, they do not.

I got this kit, do I also need a gasket between the carburetor and the V spacer? Or is the spacer the "gasket" too? Thanks

Willys Jeep Parts Tech:
This will work as a gasket as well. It may not hurt to put a thin layer of sealant but not enough to go down into the manifold.

Both 647745 and -MK show pixel by pixel the same picture. A "close look" for differences does not help. What is the difference?

Willys Jeep Parts Tech:
I'll check the images posted. The MK kit has additional linkage.

whats the purpose of the spacer?

Willys Jeep Parts Tech:
The metal V in the spacer puts a spin on the fuel/air mixture going into the manifold.

I bought the master rebuild kit. After cleaning and starting to put it together I realized there was no spacer plate on my jeep. Would you have one of these? Haven't been able to locate one on internet.

Do the repair kits come with any instructions or adjustment tips

Willys Jeep Parts Tech:
No, but we can provide if requested.
