Hey gang.. my 79 w100 4x4 started doing this yesterday. Before this it was fine.
It's a bit more difficult to start.
Once started it runs fine at 2000 or more RPM.
Below 2000 it begins to get rough. At 1000 rpm it's really rough and acts like it wants to die. If I let off the gas pedal and let it idle (normally 500-700) it just drops to idle for a second then coughs a few times and dies.
