I don't want to step on blackhawk's shoes but, the phillips screws are on a double cam bikes(79 and later) and the single cams have a slot headed screw on the carb plate in front of the carbs.
Thank you both!
It's dohc... I just couldn't find anything on the carbs... because it's in the head!
I made already a mess of it... its running really uit of tune... but i hope i can fix it now!
