I have been trying to put my g/c back on. Its on a 85 115. Everything goes on smooth, I hook up the shifting linkage, try to shift into gear and it won't move. I have taken the g/c off 3 times and made sure rod height is good. It moves fine off of p/h. I just put a new rubber gasket on shift rod w/ a new water pump rebuild kit. Before I put the new gasket on everything was fine. What do you think??
