Default idle/mixture screw positions

Long story short, I screwed-up and didn't mark the prior positions before beginning work. Car initially ran okay, but it had a rev surge which I traced to a vacuum leak in the intake plenum manifold. Now that it has been sealed the car won't start. To rule out all of the other posibilities, sensors are new and traced correct, sparks on both banks, fuel pump running as req'd. (safety switch disconnected, etc.), battery new and fully charged, AAV operating correctly.

When I've tried w/ everything hooked-up correctly the engine sputters but won't start. When the plenum hose is disconnected or a plug removed, there is a lot of fuel so I'm assuming flooded by the cold start injector. Disconnected CSI and still won't start. I'm thinking the adjustment screws which were initially set when the car was running somehow compensated for the vacuum leak, but now that it has been sealed they need to be somewhat close to their final positions before the car will start. Any suggestions, pictures, etc?

 

Thanks for the responses, however I've got an '84 QV. I found a thread from several years ago searching for 'idle adjustment' and it appears that for the idle adjustment screw.........."place a piece of paper between the screw and tab on the plenum butterfly and tighten the screw just until the piece of paper can be pulled out then tighten another 1/2 turn." It then goes on to say ......."the air bypass screw should be fully seated, then backed out 4 full turns".

I haven't tried this default position yet, but it sounds reasonable. I believe if the car will start from this point, the plenum screw should then be used to 'fine-tune' the idle to near 1000 rpm?
