Paul, I've taken several apart and cleaned them also, did you grease the rubber diaphragm before putting it back together. Most of the time they only go back one way. You might also look at the pictures on my Talk & View page under reference, it might help.

Put it together and its worse than before, could I have put it back in the wrong setting?? if so how can I check if its right and line it up with the right vacuum outlets?? >>
