Using calipers I figured out that the orings needed on the carb are 13/16" ID (inner diameter) and width of 1/16". In Oring lingo this is called a -019 according to the AS568A standard. The Honda dealership wanted about $32 for a gasket kit for the carb that wouldn't even replace both of the orings required. There is one oring of this size between the carb and the vacuum connector(that goes to the bottom of the petcock) and another between the same vacuum connector and the piece sticking out of the engine. Maybe I'll add a picture to this sometime soon so you will understand where these rings go. I said forget the Honda dealership and went hunting for these rings. I went to a carquest autoparts store and they did not have this size and then I finally decided to try my local Ace Hardware. Low and behold, they had an entire wall of orings and one was the exact size needed. Now, I'm not sure if it is the proper rubber for gasoline so I also ordered a set from http://allorings.com. You want to order the Viton Fluorocarbon material and the size of -019. The ordering page can be found here.

Location of these rings are the following...
