Need DelLorto Carb rebuild help

#1
I am rebuilding the DelLorto carb for my M5A motor, and I got it all apart, cleaned up, and pulled out all of the gaskets and orings I saw (only 4 of them), but I am left with the 3 black ones pictured. One looks like a plain old flat rubber washer, and the other two, look like they are meant to fit over something. I have NO IDEA where these three are supposed to go. I thought maybe one went over the fuel filter screen, but all three are too small (i put one on top of the screen to show this). Is there even supposed to be an oring there, or is the filter screen supposed to act like one?


Here are the ones I replaced (probably called by the wrong names, haha):

-the o-ring on the fuel cup/pan where the float valve is
-the gasket on the piece where the throttle cable goes in
-the cork gasket for the air filter
-the small gasket on the screw that holds the "fuel inlet" on



I hate having "extra" parts, so any help with this would be greatly appretiated.
