Yeah, it sounds like your 2/3 rod is not letting the lever go fully into the center position so that the 1/R lever can move smoothly.
Like 66 said, make sure it's all adjusted. If you remove the rods, can you move the two levers on the trans back and forth into the different shift positions easily? If so, you probably just need to adjust them. If not, then it might be something amiss inside the transmission.
There is an aligning hole in the two shift levers/arms (the ones on the steering column) that you put a small drill bit through to hold them in their center position while you adjust and attach the shift rods. But for any of that to work, both shift levers on the tranny should be in their center positions too.
