All questions will be displayed after moderation. All answers will be displayed after moderation.

Is this a single use gasket? (I.e. should it be replaced any time the carb is unbolted off the engine?) Also does it matter which way it goes on as long as the V is facing down down? (I.e. there is not “left” and “right” orientation)

Willys Jeep Parts Tech:
As long as in good condition you can use multiple times. The V goes down into the intake.

What is the purpose of the V? Does it make it more efficient? Does it add horsepower?

Willys Jeep Parts Tech:
I believe the idea was to put a spin on the fuel air mixture.

Will this carb to manifold gasket work on my 42 GPW? I was going to order a solex carb from y’all and this gasket but it says 45-45 GPW so wanted to make sure it would work.

Willys Jeep Parts Tech:
Yes, that is right. It is proper for you. Thanks!

Do you have a part number for the paper gasket to use with the diffuser?

Willys Jeep Parts Tech:
This is just the gasket - 648977. Thanks

Do you need this gasket? When I got my MB it did not have one.

Willys Jeep Parts Tech:
I would recommend it. They are shown in the original manuals.

How thick is the gasket

Willys Jeep Parts Tech:
It measures out at 1/4" thick. Thanks

Is 1 3/8 centerline for this gasket the same as 2 3/8 hole to hole for the other gasket?

Willys Jeep Parts Tech:
Not sure what other gasket your referring to. Please email happy to help.

I suppose these were originally designed to make the Carter WO carburetors work better. Will they make the Solex replacement carbs work better too?

Willys Jeep Parts Tech:
You can use them on the solex as well.

What is the purpose of the metal V? Does this get installed mounted up or pointing down? Do you need another gasket for mounting the carburetor?

Willys Jeep Parts Tech:
Pointed down. It put a 'spin' on the fuel air mixture. Another gasket is not necessary.

Is this the same gasket that comes with the carburetor- item #: 923806?

Willys Tech:
They use a paper gasket with the 923806. We do recommend getting this gasket as well.

Will this work on an m38 with a carter ys carb?

Willys Tech:
Yes it will mount up.

My studs stick up too high and hit the body of my carberator, will this gasket elevate it so that this doesn't happen?

Willys Tech:
It should solve your problem for you yes.

Which way does this mount? Does it mount like the photo above or does the V point downward?

Willys Tech:
The V is pointing down into the manifold.
