4GC Rebuild question

[Brtele]

I’m putting my cleaned 65 401 4GC carb back together and I’ma little concerned the gasket pictured will provide a vacuum leak between the primary throttle plates and the bowl connection. Am I looking at this correctly?

 

 The “shiny” area on the throttle plate is a different pattern than the gasket. 
 

Thanks for the help.

For what it’s worth, the new gasket is identical to the existing gasket.

Did you use the search function on the RIV section of the forum, using a couple of key search words? I believe this subject has been addressed before. John

  That`s the gasket I referred to in your other thread! Here, toward the last postings:

4GC use at least two different bowl-to-throttle plate gaskets, both of which should be in a rebuild kit. Using the incorrect gasket will create idle and vacuum leak issues. Go with what carbking says unless you have a factory shop manual.

 

My view on 4GC is that they're either very good or junk. I had one that I fought with for more than ten years. I smiled the day I threw it in the dumpster.

Good night, I had the gasket upside down in the initial picture. Once I flipped it and read carbkings’ linked tech article, it makes more sense.

 

I’ll also try to do a better job of searching before posting per jolly_john’s recommendation.

 

Thanks everyone.

 

EDIT - I REMOVED THE IMAGE AS THE GASKET WAS INCORRECTLY PLACED IN THE PIC AND DIDN'T WANT TO CREATE FURTHER MISINFORMATION.

Brandon,

 

    The way the gasket is on the base now is WRONG. On the bottom right you can see it will have a vacuum leak. The gasket NEEDS to be flipped over.

You’re correct, there was only 1 way the gasket would fit on correctly when I placed it over the gasket guide pins. Thanks

Glad you solved your problem, Brtele. That always feels good, doesn't it? I hope your nailhead is now running great. John
