Inlet manifold question

Underneath the manifold there is a circle little thing near the temp send thingy. is there supposed to be a little hose coming off the little pipe it has. if so, where does it go.

the hose off the little circle thingy (only on egr manifolds) goes to the thermal vacuum switch which is the one on the front of the inlet manifold. should also be one going from the vacuum switch to the bottom of the carby (if you've got a nikki)

the black cylinder looking thingy (altho I don't like to be that technical ;op) i think you're talkin about is the evaporative control valve. one to the sump, one to the aircleaner and one to the fuel tank

my last concern is the 3 little plugs on the bottom of the carby. On the engine side of it. do they have anything to do with the one on the rocker cover.

cheers,

2 little ones on the engine side of the inlet manifold - back one goes up to the air cleaner front to the rocker cover. other plug at the front on the bottom of the carby goes to the vacuum switch i mentioned before.
cheers

on the inlet manifold, facing towards the passenger side, at the bottom of the carby, there is 3 plugs. shaped in a triangle from. I think the setup that was on it b4, was the 2 top plugs ran into eachother, and the bottom one had a bolt in the hose to block it. then the rocker cover hose, went straight to the aircleaner. That doesnt seem right.

yeah sorry, don't know much about them. just thought tho' 2 of em have gotta go where I said, the other hmmm. something to do with the mechanical fuel pump?? Do you still have the late model head or a pre TF head with no mechanical fuel pump?

okay the tube that comes off the the rocker cover goes to the first tube on the inlet manifold it is the PCV valve. the middle one goes to the egr valve. The last one goes to the air cleaner it is a vacum line for the idle ( apparently)
i f u have the wevber jsut block that one off.
