Yes Trev you are right.
I couldnt see an advantage taking the shaft out, the split pin was pretty hard to move aswell.
The smaller venturi stops it from the filter side.
The 3 dimples on the plate are meant to be orientated up.
The only way I could get it into the slot, was to grind the dimples on the plate down.
Working with the angle I had.
Found a screw with a tight fit and used blue loctite.
It is back together.
