o.k this will be simple for those with a car near them, i need to know where the distributor gets its vaccum from, mine comes directly from the carbon canister, and i know that aint right, i just cant find any diagrams in my books of it, so please help, and a couple people look please and report in case someone elses is been messed with, oh mines a 79, with the 60 mm tb, so the thingy on the bottom of the tb is gone

 

The distributor get its vacuum from the TB. Do you have any fittings for vacuum on the TB at all? If so, and it's already being used, then just splice in a T. Otherwise it's no vacuum advance. You can't source from the manifold cause then the advance would be engaged full time. Where is your charcoal canister getting it's vacuum signal from? You can splice into that.

 

the tb has one port in it, and the canister is getting it from the manifold, so full time, so that prolly why it advances the timing all the time, what about the little one way valve?

 

T off the one fitting on the TB and install the one way valve so that the side you can suck through is facing the TB side. You should be able to suck through that side (the TB will suck) but not blow through that same side.

 

were should i put the one from the carbon canister that is currently going to the dizzy? does it control somethig, maybe egr? it has vaccum sucking through it

 

T that in with the advance line. But put the T between the check valve and the TB. The canister uses a pressure differential type diaphram so you'll want that vacuum line hooked up.

 

On second thought, explain the hose routing for you canister. All the hoses.

EDIT: You should have one line to the intake manifold and one line to the TB. The other line goes to the fuel tank. Turbo's have one more line.
