First time mods on my 318 and it won't start...

Wow, you guys are quick!

Just to answer your questions

• can't check timing yet (tool is in the mail...)
• haven't done anything with the ignition system (apart from removing & reinstalling the distributor)
• car ran fine with old manifold and carb
• engine does run a few more seconds before dying when I keep on cranking
• rear vacuum port is shut

@H22A4: very nicely described and I admit you are right (just leave the aspargus, hate that...;) ). I know I'll have to tackle the transmission-linkage before it can drive but for now I just wanted to see if the whole setup generally works; does the engine start, how does it idle (does it at all)? Then fix what I've for now considered to be secondary issues.

Thank you all for your suggestions so far (and H22A4 for straightenig me out a bit :) ).
