Ted,
The Shop Manual shows/mentions no gaskets.
However, I'd say that almost everyone uses a gasket between the carburetor and the spacer/insulator. Be sure that there is a notch in the gasket to match the hole in the base of the carburetor.
The gasket between the spacer and manifold is probably not used by a majority of people, unless there is a leak or unless they want a failsafe against a leak. Using a gasket in that location causes no harm.

My existing setup that came w/the truck also has both. | | | | | Joined: Oct 2010 Posts: 1,232 'Bolter | | 'Bolter Joined: Oct 2010 Posts: 1,232 | Ted - I wrote a similar response to another post recently. I don't use gaskets with the insulator on my '54 3100 235. I have no leaks. Gaskets raised the heigth of my carb thus making the accelerator rod to the carb too short. The throttle butterfly would not open fully. The insulator and carb rod are originals that I purchased from forum members. It's possible that they are from a different year 235, or that accelerator rod assembly bellcrank is worn, but bottom line - everything works.

I can see where if I install the insulator and gasket, there probably will be a problem with my accelerator rod not being long enough. I have a extra rod, and it and the one on my truck are the same length. How in the world would the insulator and gasket have worked with either of these rods? How did they come from the factory? Is there something I am missing here?
