Throttle cable issues

Throttle cable issues
I have a 95 FLHT. 89",Super G carb.
I am having problems with my throttle not snapping back.
I bought new cables and installed them and the problem has not gone away.
The return spring on the carb is strong and will close itself easily.
I have turned the throttle lock off.
If I connect and tighten everything and adjust it, I only get about half throttle.
If I loosen the two screws that clamp the housing to the bars I can get full throttle but I can feel the throttle sleeve hang up as it tries to enter the lower housing.
When I tighten the screws it stops the throttle from turning at that point.
I cannot see any reason for this to hang up.
The throttle springs closed properly up until it starts to hang.
Should the cable connection for the return cable be going into the bottom housing?
Has anyone else had this problem?

Yeah on my few months new to me 96 RK, orig CV carb. The (looked) original cables wouldn't allow the throttle to spring closed. It was bad enough that it was pretty much a cruise cont even with the throttle tensioner thumb screw out. I pulled the controls apart up top and used a needle oiler to lube the cables. No change.
New Barnett cables weren't much better till I did some adjusting and slight re routing to make the turn inside the headlight nacelle less of a sharp turn. I also bypassed the little metal cable clamp on the frame under the tank. They didn't like being routed thru that at all. Now they work great. I did have the tank off thru the cable change. The new cables are very sensitive to adjustment. Just a little too tight and they start getting slow to snap the throttle closed.

I have the tank off.
I have the fairing off.
The cables are not tied anywhere so routing should not be the problem.
I pulled air filter bracket off.
The carb is a slip fit to an Edelbrock manifold.
I can't change the manifold because the heads have been ported to match the manifold.
The intake ports are rectangular rather than round.
The cables are correct at the housing because the have different thread sizes.
I have the pull cable at the carb in the rear shorter barrel.
I have the return cable with the spring in the front longer barrel.
It seems like the problem is in the throttle sleeve.
I can get the cables to work fine up to about half throttle.
To get full throttle I have to turn the the throttle sleeve past the point where it wants to stop.
I bought a new throttle sleeve from HD and it does the same thing.
I think I need more travel at the throttle sleeve.
At rest the throttle sleeve is at the mid point.
If I could start it rolled off further forward I think it would give me full throttle without trying to roll down into the lower throttle housing.
Is there an adjustment for this or does it always want to be at the center?

I have a 94 flstc with the stock carb but cause I like tall bars I've changed my cables a few times the last set I got were way too long, just got them set the other day. the book says to start with both cables backed all the way off, then adjust the pull cable at wide open throttle with the tire straight, till the throttle reaches the stop on the carb. then turn the wheel to the right till it stops and adjust the return cable to remove the slack. hope it helps

Let's just stand back for a moment! Has this throttle worked OK for you in the past? If it has done, is the current problem a recent one? If so have you made any other recent mods, like changed the handlebars? If it has been fine in the past, it can be fine again in the future - we just have to wrestle this thing until we have it cracked!

It was working at one point.
I started having problems with the throttle not snapping back as it should.
I haven't changed the bars or made any adjustments until I replaced the cables.
I have adjusted the slack out of the pull cable and adjusted the return cable until it closes properly.
I am still not getting full throttle.
