Take the cable off at the engine again and see if you can shift the motor manually to all three positions. If you have the engine off, pull the plugs out and you can turn the prop and make it easier to check.

OK, so we know that your problem is in the cable somewhere. Is the control arm moving all the way back when you try to go in reverse?

no i can push lever forward fine.but then when i go to pull it back to netural ,it stop right before netural when the button under handle should click in.will not go past that point.this even happened when i had cables off motor end.

Yes, it sounds like the problem is in the control.

Do you have the control with the black leather arm rest on top, and a toggle switch for the choke under the ignition switch?

no toggle switch.it has a lever on side by throttle lever that you pull up to choke or rev up when not in gear.if you go on e-bay and look at item 130196885098 that is what my looks like.the only diffence is my has power tilt switch on side of throttle handle.thanks for all the help.

OK, the little ball bearing is in front of the detent spring and it can be moved and the spring can jam the arm. That is just one possible problem.

You will have to open the control to find the problem.

It's hard to relate anything to simply removing and reinstalling the control. I sort of suspect the shifter arm and rotary plate are worn. They have what I refer to as a "one-toothed" gear for lack of a better description. When excessivly worn they jam up. As said, you will have to get in there and looksee.
