Check REAL CLOSE  for a vacuum leak. Usually when the engine won't respond to turning the idle screw the FIRST place I check is around the base of carb/manifold for a vacuum leak. You DID use a new gasket....right?!
I would totally disconnect the electric choke until the idle situation is fixed.....then adjust the choke.

Ciao Alessandro,
check also if PCV valve properly work and tubes are right connected.

Sei l'Alessandro degli Heddman Headers?
Io ho tribolato parecchio con il settaggio del 1406, ho anche acquistato il kit di getti e spilli per migliorare la carburazione perché il 1406 rispetto al 1405 esce settato con carburazione più magra. Attualmente ho reinstallato il vecchio 2100. Ciao.

Ciao Marco , si sono quello degli headers ,  ho appena montato il 1403 e non sembra andare male . Per ora niente fumo eccessivo , solo il minimo alto e il chocke da rivedere .  Sicuramente un  kit mi sarà utile in futuro . 
Gli  headers  mi piacciono molto e metterli è stato abbastanza semplice . L'unico difetto è l'altezza da terra che preclude ogni dosso o entrata in discesa . Sono molto bassi e con gli attuali silenziatori l'auto è abbastanza silenziosa . Per me un po troppo silenziosa ma posso sempre fare meglio . 
Nella parte dedicata alla storia della propria auto ( in questo sito ) c è anche la mia storia , se ti interessa è titolata my mustang starting resto .  

Ps  : non è che per caso hai un 302 che avanza ? o qualcuno che vende non crepato a prezzo ragionevole . Anche solo il blocco . 
Ciao ! 

TRANSLATE IN ENGLISH

My reply was :  Hi Marco , yes i am !  I just installed the new 1403 and seems working fine , no dark smoke, needs a set up with choke and idle speed .  Probably i will need a kit calibrating .
I like the headers , easy to mount but they are very low on the ground and speed bumps can be an issue . 
With muffler sounds is not loud , but i can do better . 
In this site there is a page dedicated to car story , if you want to see my story let see " mustang starting resto " . 
Bye 

Ps : maybe you have a 302 laying around, at low price ? 
Ciao ! 

This is the translaction from italian . 
hope it helps

Dear MS it was a simple presentation because i bought headers from him and  he recognize me in this forum. 
I didn't know that it was a must speak in english , and this was not intended a long story in italian . Now i will translate what we speak about .  Next time i will speak in italian out of this forum , or i will write in both language if allowed .
