Re: Time to put that Carb Spacer in!

Thanks yucales! Your post motivated me to go pull the carb off again and check more closely. For this phenolic (plastic) spacer, you MUST install with the hollowed out cavities facing up and the smooth/flat side down on the intake.

It isn't obvious, but installed wrong the shape of the spacer prevents the throttle assembly from fully returning to idle.

Hope this helps someone searching carb spacer. I looked and wasn't able to find anywhere that describes how to install these correctly. One picture in the package would have saved me a lot of time and effort!

Re: Time to put that Carb Spacer in!

I have the 1/2" laminate wood spacer under the AVS2 on my BB 366. It did solve some of my issues, but on a good hot day I still get hard restarts. I ordered the square bore style spacer to match my manifold and carb, but was sent the performer manifold type with two large ovals. I'm guessing the mismatch isn't insulating properly?? Swapping out for the correct one is on my to do list.

Man, it sucks that you had to do it twice, but thanks for letting the rest of us know that there's a difference of the sides to be aware of!
