These are a couple of links I used when I first waded onto the Syncro pool.
Campagnolo Syncro II shifters ~ tears for gears

I you follow the “Syncro” tag link on the tears for gears site it will pull up a couple of more articles.
I don’t think the brass washer next to the baseplate stop is in the proper place. The “mushroom” piece may also not be all the way seated onto the down tube fitting. When you insert it into the shifter body, rotate it with you thumb until it falls into place. You may have to rotate the whole shifter to do this, it’s been a couple years since I last set one up.
Quick pic of mine
