I had similar troubles with my MT 71. I found that I could not drive around 
town at a casual 30 mph in 4th gear. No matter how gentle I tried to be, the 
drive train would eventually start to lurch back and forth as if, like you
said, I didn't know how to use the clutch. Nothing I did cured it completely, 
but a number of things seemed to help.

I went thru the CV joints and cleaned them up, replacing those with lots of 
backlash. I even swapped balls around among the others to reduce the play.

I tried reducing the fuel pressure, but that didn't help.

I made sure the throttle valve switch was correctly adjusted and that didn't 
help.

I tried different brains and pressure sensors and that didn't help.

I ended up just staying in 3rd gear at that speed.

If I had it to do again, I'd try taking Russ's advice and putting the fuel 
pressure up 1-2 psi.
