The brass extension is called the secondary well.


It sounds like there might be a misunderstanding on the name of the parts.

Also sounds like maybe some previous owner installed parts in the wrong locations.

1. The idle jet is next to the venturi (but the long end of jet) does not go into the venturi it goes into the secondary well.


2. The idle jet screws into upper casting and the longer end goes into the brass secondary well located in the lower casting.

Please scroll through all of this page and look at all of the photos and descriptions of the parts.
