Thanks Steve,
You are corret, it is K-jet, I checked the manual.
Your comments agree with the mechanic I spoke to at the G dealer. He also mentioned a possible mixture adjustment. I haven't had the truck for more than a few weeks and I am just starting to get it sorted out.
I am going to remove the intake in order to replace all of the vacuum lines hiding under there. I will try to clean the air valve if it is at all servicable. I need to do a valve adjustment and set the idle mixture and check the timing. It also needs new plugs, wires, cap rotor. I seem to have my work cut out for me
