The third picture in the group,of pictures shows the stock 3310 housing/ball.diaphragm.
You have to put the diaphragm in correctly so that the hole is above the ball and the ball has room to move upward. The diaphram thickness is enough to allow the ball to unseat because the ball sits below the vacuum diaphragm housing with a stock set-up.
I have several of the quick change kits down stairs, I will look at one of them tomorrow evening and post what my parts show.

Otherwise I could send you a proper stock set of parts.
