mikuni idle screw?

[frankyaxs400]

hey everyone
ive been having a hard time locating anything on my mikuni carb for my 1984 xs400 seca.
our goal is to tune it when we get it on the bike

im looking for the idle screw but cant seem to locate it, and ive created this account to get help with it.

but anything will help, fuelscrew? idlescrew? anything..

Idle air screw? If so its located right on top in this pic I know the pic is upside down but look at the carbs from the top. There may be plugs in there but not sure as mine did not. You have to go through the choke bracket to get to one of them.

Your idle screw should be next to where the throttle cable connects to the carbs. Your looks to be missing. Post a pic of the side of it.
