Carburator Manifold Issue

Some of my spark plugs are burning rich and some are perfect. The 2nd and 4th in on driver side and the 5th and 8th in on the passenger side are the ones burning very rich. I changed the wires to see if I had bad wires and the same issue. I have a 1406 elderblock carburetor. I read Jason's post on the carburator and pulled the carb and noticed the holes in the "gutter" were not plugged. I there were no other holes on the top of the manifold. Any one have any idea's and should the gutter holes be plugged? I do not have a heat riser either nor can I see the underneath of the manifold.

Comment by Dominic Salemi on September 26, 2015 at 7:13pm: Yes motor recently rebuilt. Cap & rotors new and the cap looks good unless I can't see a crack in it. Should I have my dist. checked? I have an electronic dist. and coil. I have new wires and even tried switching the wires around. I'm almost ready to go buy a new carb. This one is about an 1 1/2 old. Is there a machine that can check to see if all cylinders are firing properly?

Check and clean bad plugs first.

Plug the back of the carb. vacuum lines ..even the tranny line. Keep the vacuum advance hooked up and run car. Will I be able to drive the car or will I have to idle it?

Thanks

1963 RHS A/C kick panel - photos needed

Posted by SK on June 2, 2025 at 2:20pm 2 Comments 0 Likes

Could someone post front and back photos of the 1963 right-hand kick panel with A/C?

My car didn’t come with the original kick panels, so it's a bit of a mystery to me how I should cut the backing board and carpet to fit around the A/C.

Many thanks,

-Samu

Loud air moving sound within carb with cleaner removed

Posted by Dave Fehrle on March 23, 2024 at 3:23pm 8 Comments 1 Like

While checking my Carter carb with engine running, I took the air cleaner off and there was a very loud hissing sound of air. I placed a piece of paper over the carb and it didn’t move up or down, is this normal?
