My 68 New Yorker (owned many years ago) had the same air cleaner design. It didn't make sense to me how enough air could get through that small opening especially when you compare it to hugh opening in the top of the carburetor. So to allow more air to get in I flipped the entire air cleaner over and drilled a string of 1/2" diameter holes around the bottom just outside of the filter element. Once the air cleaner was back in place the holes were not visible and all air that came through the new holes still had to go through the filter element. To be quite honest, I don't know if I improved anything or not. The car still ran like a spotted ape and still got 10 mpg.

Doesn't this choke the engine on my 67 Imperial? Chris ----------------- http://www.imperialclub.com ----------------- This message was sent to you by the Imperial Mailing List.
