2013 Exped - Max fuel question

[fothco]

Can I adjust mixture : gas + air ? When starting cold , the smell of gas ( exhaust ) is high . No leak but odd ...
Days gone by we had carburators , chikes , fuel mixture adjusting screws etc ..

Now , how do I adjust my 5.4 L Gas Ford engine for these settings ? fothco
