1952 Super A - need to know if a carb jet is pressed or screwed in

[Sayre]

My intentions are to rebuild the Zenith carb on my Super A, but before I order the kit I want to get all the parts out. I'm having a fit with the small jet in the upper, down facing part of the carb body. I need to know if the jet is pressed in or if it screws in. Any info will be greatly appreciated.

About the only parts that fail here is the needle and seat. Soak well and be sure air can pass easily and you should be fine.
