Yes and the two little o rings , itty bitty one that goes around the jet and some have a o ring in the bottom of the bowl.
You can normally get a kit for your carb for about $9 that has all these parts plus other parts. (on fleece bay or otherwise)
Post u[p a part number for the carb you are currently working on and maybe we can then point you towards a kit.
Usually if a Nikki is old and you pull it apart it likes to have new gaskets and o rings when it goes back together.
I have taken parts like the rubber gasket and o rings from the New cheap clones that were not running smooth and make a real Nikki operate ok, but one size does not fit all when the Nikki's are in the loop, different bowls and some difference inside and the jet might be a different size so you are rolling the dice trying to take 2 or 3 and make one.
I have had to return some Amazon Nikki's that would not run correctly.
The Old Walbro LMT carb's are usually to most user friendly on those engines. Briggs used them few years ago before they went to the Nikki and Ruxing carb.
Here is a link to a used LMT on fleece bay. Also here is a link that shows how to repair both types of carbs. Walbro LMT and Nikki plus others
