On my 17080213 carb im rebuilding

Am I supposed to have the black plastic cup insert installed as seen and on page 12 of Cliff"s book

This ebay bought, previously rebuilt carb did not have a plastic cup in there when I disassembled it. Maybe this year carb doesnt use need that plastic cup?


(Plastic cup would be located in the round area under where the yellow pencil is laying across, shown on page 12)

I dont see the round plastic insert part on Cliffs parts site.

Cliff do you have that piece, so I can add to my parts order?

Early M4 Qjets often had the cup insert, later on it was omitted from factory. Not needed.
