Carter 4 barrel base gasket question

Posted by Chris R On 2021/3/26 13:12:51

Hello all,

Since the carb is all freshened up, I thought it would be a good idea to replace both carb base gaskets while I was at it.

I was hesitant to pull the base insulator because I was afraid it would brake due to it's age. Well... It broke...

So, I'm going to order a new one from Max Merritt. While I was poking around on their site, I noticed the factory style base gasket design.

It looks as though, there is a cutout where the two holes of the base insulator line up to. I also looked under the carb and it looks like there is a channel or cutout on it as well.

Does anyone know what the purpose of this channel or cutout is for?

Thank you,

-Chris
