I will do that. This truck also has about a 1" throttle body spacer between the manifold and the carb. I noticed there wasn't a gasket between the spacer and manifold, so I added one. I also have one between the spacer and the carb. Is this the correct method?
A gasket isn't supposed to be required between the spacer and manifold.
I use one because I had a vac leak there even though a straight edge showed the manifold was straight.
A gasket is required between the spacer and the carburetor.
