Well I got it shifting now. The vacuum hose for the modulator valve has disconnected from the carb end. I did not find the original location after looking for a while so I connected it to a tee that had a cap on one side.It is probably not the correct location but I did not find a connection for it. It shifts smoothly all the way to third. It downshifts when I step on the accelerator. The carb does sputter some now.
