Hello, and welcome to the forum. Slip over to the introductions and tell us a little about yourself and your Patrol. What engine do you have? If it is an RB30, @dom14 has posted a fair bit about the carby. http://www.nissanpatrol.com.au/forum...l=1#post615203.

If it is a TB42 then hopefully a knowledgeable member can help, or you can download the workshop manual from this forum.
