My project came with incorrect manifolds and carburetor, so I have been collecting bits and pieces to eventually make this thing go.
The intake manifold I am now planning to use came with a gasket between the phenolic spacer and the manifold itself.
I would guess that there should also be a gasket between the phenolic spacer and the carburetor base...but I almost think I read somewhere that there should not.
I have tried to find an illustration of the assembly: manifold, gaskets, spacer, carburetor - but have not found one so far.
Should there be two fiber washers gaskets in that stack?
Do the pieces in the photo look to be correct? (I would replace the fiber washer gasket that was between the manifold and the spacer with a new one.)
Thanks!

Yes, a gasket should be used on each surface. Any imperfection in the manifold, spacer, and/or carburetor surface needs to be sealed completely, those soft gaskets are designed to prevent vacuum leaks.

I don't have a gasket between the carb and spacer. I know some have chosen to put one there; if you do, make sure that you do not block the vacuum port for the power valve.
