Here are some pictures, just to be sure.

This first picture of the engine iw without the intake crossover pipe, the throttle linkage being at the lower right-hand corner, so I think.




Next pic of throttle housing with it closed:




Next pic of throttle housing with it opened, WOT.


A little hard to see because of the angle, but it's all the way open.


Now my questions... what in there do I lube? Just each end or whatever!? Maybe it's as simple as that...? I just keep hearing all of these parts that need lubrication, but don't see many down there! THanks again.
