Regarding the youtube video referenced above (post #28), the fuel distributor used for the "demonstration" is from a K-basic system, and the diaphragm valve springs operate in a manner that is the opposite of those found in the KE fuel distributor, which is the subject of this thread.

Thanks Frank, all these replies have given me more hope. I will be splitting the FD again just to make sure that all the ports are perfectly aligned on the fuel spindle with the FD body as well. I'll find out tomorrow and report.
