Leaky cold start valve? I have a motorcylce that with carbs (I know, not related, but..) that have been jetted. When cold it starts fine, when warm, it floods very easily and will take a lot of cranking before it starts if it starts at all. Usually draining the battery a bit, then I let it sit. Anyways, the point is, with all the new parts you listed, you didn't mention the cold start valve. Like you, I have problems with my CIS (78 SC in my 76S), I have checked or replaced nearly all the components, but the cold start valve.

My guess (smack me on the back of the head if this is on the wrong path guys) is that the cold start valve is leaking causing your pressure drop and a very rich condition on starts, hence you nearly endless cranking before it starts. Just a thought. I'm going to try to replace mine soon. (Just got a new bike so it'll have to wait for a couple of weeks).
