Question: the carburetor schematic shows a gasket that goes on top of the Insulator Plate, between the Carb (throttle body) and the insulator plate. Should there be a 2nd gasket that goes on the bottom of the insulator plate between the insulator plate and the Intake manifold? OR just the insulator plate on the manifold no gasket? | | | | | Joined: Jan 2000 Posts: 2,074 'Bolter | | 'Bolter Joined: Jan 2000 Posts: 2,074 | Nope don't think so, should be ok. If worried can spray some B12 at that area with motor running and see if she speeds up. | | | | | Joined: Jun 2004 Posts: 8,597 Riding in the Passing Lane | | Riding in the Passing Lane Joined: Jun 2004 Posts: 8,597 | I like to put a gasket on both sides of the insulator.

The Master Parts Manual refers only to a gasket between spacer and carburetor.
I always use a gasket between carburetor and insulator (with the cut-out properly oriented).
I have sometimes used a gasket between spacer and manifold (if the mating surfaces were not real smooth).
I have never had a leak when I did not use a gasket between the insulator and clean/smooth insulator and intake nanifold. | | | | | Joined: Jun 2016 Posts: 102 Shop Shark | | Shop Shark Joined: Jun 2016 Posts: 102 | | | |
