31 late model carburetor

[sphooch]

Hi Guys, happy new year to everyone. question : I am attempting to rebuild a 31 zenith 1 carb. in the disassembly I so far have 2 questions 1st the jets all have double fiber washers on them however the Paul Moller book on repairing these does not show 2 washers only one could there be a reason for washers on a previous rebuild? and #2 is the venture I removed has a small gasket on it but no where can I find one in the disassembly guide? can any one shed some light on this? and is the venture suppose to be pressed in or should it fit loosely. thanks the hooch
