Carb diaphragms and slide question (aka: found the problem!)

[bosozoku]

I still couldn't get the carbs to sync, so I pulled the airbox and looked how the slides were behaving.  To make a long story short, it turns out that the right carb diaphragm was much stiffer than the left, causing the right slide to move less and the diaphragm to sort of "stick" and not stay in the proper resting position.  I replaced the diaphragm with an extra one from the carb that I bought.  Now the carbs sync much better, though still not perfectly.

I should really get two new diaphragms and install them.  They're $16 a piece OEM, and I might finally have two equally behaving carbs.

One other question on slides: the slides from my original carbs have one vacuum hole in the bottom with the other hole plugged with a white plastic piece.  (Those holes are beside where the needle passes through the slide).  The open hole has a sort of plastic restrictor in it as well.  The slide from the extra carb just has two large holes beside the needle hole.  Which setup is "correct" for 1993?

Blocked holes = DJ crap. You're gonna have to get matched ... like swap the good diaphragm onto a blocked slide.
BTW, why were the slides not behaving identically one had blocked, other did not

Nope, I was using both blocked slides.  One just happened to have a bad diaphragm.
