Adjusting idle speed

Got my carbs back from Randy, got them on, and it start and seems to run pretty good, but doesn't want to idle, so I'm trying to turn up the idle speed.
So, the idle speed screw is "upside down" and turning it counter-clockwise as you look at it from the side should increase the idle speed, right?

Clockwise will increase the idle
unless you ride bikes, I mean really ride bikes, then you just won't get it

84 Fj1100 absolutely stock standard, now more stock , fitted with Fj12 twin system , no rusted headers for this felicity jayne

Correct,

Counter clock wise to increase the idle speed.

From the right side, push the front of the screw towards the left.

OK those two answers contradict each other  :lol:
So if I'm laying on the floor under the bike looking up at the screw, which way do i turn it to increase the idle speed?

If you could grab onto the adjuster with your hand, then turning it like you're screwing it in, or up, or like you're tightening it will raise the idle speed.

If I hand you a jar and a lid and tell you to put the lid on the jar, that's the rotation direction for the adjusting knob to raise the idle.  Doesn't matter if you hold the jar right-side up or upside down, the lid always screws on the same way.

You're actually screwing the adjuster so the threads push the throttle linkage upward and open the throttle plates.

I turned the screw in until it seems like it's bottomed out but it still won't idle long without a little throttle. I can give it a little throttle and keep it at 1000 or 1200 rpms, but if I let off the throttle, it slows down and then dies...

Billy,

Did you look at the throttle stop for damage from shipping?

I pack them to prevent any damage but it does happen.
From there, call me tomorrow.

It looked good, and everything seemed to worked fine.

As has been covered a number of times, sort of, you are turning the screw clock wise (if you were looking up at it from under the bike) to raise the revs.

What makes it easy is if you crack the throttle a little it unloads the screw by lifting it off the stop, this makes it much easier to turn.
