Sweet find, I am going to follow this build.
I rebuilt the fuel distributor in my 930 barn find.
The center piston was completely stuck, I had to split the upper half from the lower and then hammer the piston out. But if your careful,. and keep track of all the little parts it's not that hard to rebuild. This is a good excuse to get an ultrasonic cleaner.

I have not done the warm up regulator yet, but there are plenty of videos on YouTube.
