new problem with throttle on 150 johnson 83'

[bcraigan]

I posted a picture here of my new issue area. The large white arm in the center will shift forward, but is pretty tight. The big problem now is that there is a s shaped piece of metal coming off the top of the center white arm. It attaches to a black plastic piece that is attached to some arm coming out from under the fly wheel. basically it forces what ever that arm is foward when the arm is pushed foward by the throttle cable. Well that s shaped rod coming off of the top of the white arm in the picture will not stay attached to that small black piece of plastic now. Any ideas of what to do? Thanks for any info. craigan.
