I am looking for information on the folowing:

What is the proper head bolt torque ? Mine is currently set for 70 ft lbs.
What is the propper tappet clearance ? Mine is set at 17 thousandths.
What is the primary setting setting for the oil pump adjustment? Mine is set at 6 turns, and I do net get enough oil pressure. At 2 turns I get too much oil pressure. I will try 4 turns next. If any one has experience adjusting this thing please let me know.
Does anyone have a service manual or know where I can get one for this crawler ?
Can anyone give me information on where to find parts (new or used) that would be great.
