2F Carburetor Insulator Plate & City Racer Carb (1 Viewer)

[brooklyn]

HI all - I am changing out an older carb replacing it with a City Racer non-smog carburetor. I also purchased a new insulator plate from VintageTeqParts. After reading a few threads, I want to confirm that no additional gaskets are needed between the manifold and carburetor as the insulator has gaskets. Is this correct?

Also, when mounting a new out of the box carb do you do any adjustments to the carb before installing?

Looking to get this all installed on Friday and want to make sure I am ready -- thanks for any insights.

I’m not positive but I think you need you a spacer between the top of the carb and air cleaner. City racer sells the spacer.

When i replaced my webers with new oe non usa carbs i had to play with jetting as both were wayyyy too lean.

Why is the carb insulator cut in 1/2?

No gaskets with the insulator. That’s correct.

The carb may need adjusting most all I’ve used just need RPM

NO additional spacers between carb and intake and spacer / below carb base


some set'ups require a spacer tube above the air horn ?


RACER sells them , not sure the exact why behind this ?

The insulator come with the gasket as pictured above— no need for anything else if you received 21912-61035.

Agreed what Grogan said: either it’s the picture or the carb insulator plate has been chopped in half.

Picture to show full plate && thanks for the advice on gaskets. This is going on tomorrow.

Insulator plate and carb installed. Getting the most slightest gas leak around this connection - really just moisture. Any tricks to getting this to be perfect.

You need an "olive" as shown in ToyotaMatt's post above.

Was it determined that the insulator was normal? I just rebuilt my 78 carb CA and was wondering if the divided ports on the insulator were correct. There is a vented screw going up through the throttle body into the main body of the carb. When installed onto this insulator that vent is "blocked" off. I've never noticed it before, but am now wondering if it needs intake vacuum up through the insulator.

Yes, before you ask... I put the fourth stud in with the carb.

There is a passage in the throttle “throat” for that screw.
