Re: Start Up Problem for a 1979 300SD?

When were the engine's valves last adjusted? Adjustment is due every 
24,000 kms.

And your starting technique: At 0 degrees C. M-B wants the accelerator 
depressed and held there while the motor is being cranked, let off the 
accelerator when the motor fires. At -20 degrees C. M-B wants the 
accelerator pumped three times before cranking the motor, then the above 
  procedure.
