I cant get my motor to slow id

I cant get my motor to slow idle.I half choke it and put the handle in start postition and it starts fine.When I take the choke off I can turn handle and it revs up fine but when I try to turn the handle into the shift or slow postition it bogs down and dies.I noticed that the roller on the carb (on the second butterfly) goes all the way in and it locks the handle up. I have to pull it back out and turn the handle back to the start postition.Is there a piece that broke off allowing the roller going to far back? Any advice would be helpful thanks.

"it sounds like u r missing a plastic roller?--
and if u r looking at decals on handle,disregard that,and just idle it down.."
 
"the plastic roller is there a

"the plastic roller is there and it rolls fine from full throttle (all the way left) till about half way twisting right which is around the slow, shift area. It stays at high idle until I enter that zone,and when I do the roller goes back toward the engine because the roller guide ends.The guide does not look broken though it just ends."

Carburetor Adjustment - Single S/S Adjustable Needle Valve)
(J. Reeves)

Initial setting is: Slow speed = seat gently, then open 1-1/2 turns.

Start engine and set the rpms to where it just stays running. In segments of 1/8 turns, start to turn the S/S needle valve in. Wait a few seconds for the engine to respond. As you turn the valve in, the rpms will increase. Lower the rpms again to where the engine will just stay running.

Eventually you'll hit the point where the engine wants to die out or it will spit back (sounds like a mild backfire). At that point, back out the valve 1/4 turn. Within that 1/4 turn, you'll find the smoothest slow speed setting.

Note: As a final double check setting of the slow speed valve(s), if the engine has more than one carburetor, do not attempt to gradually adjust all of the valves/carburetors at the same time. Do one at a time until you hit the above response (die out or spit back), then go on to the next valve/carburetor. It may be necessary to back out "all" of the slow speed adjustable needle valves 1/8 turn before doing this final adjustment due to the fact that one of the valves might be initially set ever so slightly lean.

When you have finished the above adjustment, you will have no reason to move them again unless the carburetor fouls/gums up from sitting, in which case you would be required to remove, clean, and rebuild the carburetor anyway.
