Awesome SU Site
 

After rebuilding the Z, I have been tinkering with it on and off, and I've been searching on the internet for answers to my questions. I ran across this cool site that is all about the technical aspect of su carburetors. I'd check it out if you want to know more/have any problems with your carburetors.
