What should I do with these vacuum hoses?

[Fiat88]

Here's some pics I just took today. As most of you know I switched my stock carb to a weber 32/36 DFEV, I'm still not sure what to do with these left over hoses: 3 of them have vacuum(suction) and one has no suction. My car still has a ruff idle at start up and idles low until I get to operating temp. Are these causes me big vacuum leaks? Not sure what I should do with these hoses.

I labeled the hoses 1,2,3,4. BTW, What does that UFO shaped thing do(5)?


Here's a pic of my newly painted valve covers.


What's the thing next to my coil that I labeled A?

A is your condensor, you need that little thing, that little thing helps create that big spark you need.
5 is your EGR valve Exhaust Gas Recirculation Valve. It allows hot gasses to pass through the intake to warm up your carburator when its cold. Its a big valve. If you suck on the hose it should move about 1/4 inch. And suck hard, its got a heck of a spring.
As for those vacuum hoses, I eliminated all of mine, plugged all the ends sticking out of my intake. The only one I used was the one from the distributor cap to a variable vacuum venturi on the bottom of the carburetor area. How do you know which one is variable you ask? put a hose on one, when its idling you should feel no suction. when you accelerate you will feel suction. Its that simple.

I hope this helped a little bit.

Oh, ok. Thanks.

The only vacuum hose I have attached to the carb is that dizzy vacuum hose from the distrib., that's the one you mean?

The condenser you have on your electronic ignition is to suppress noise in the electric system so you don't hear so much noise in your stereo.

well, the info is partially correct. Your condensor needs to be connected to the + side of the coil, not grounded like it currently is. Your "ufo" is the egr valve, but it doesn't warm the carburetor up. It reduces Nox when it opens by diluting the intake charge with exhaust gas. Having it operational will cut fuel mileage about 10%, and will cause a stumble on acceleration if you connect it directly to vacuum instead of through one of the thermal vacuum switches. Personally, I'd disconnect that line and plug it.
You mentioned the only vacuum hose you have connected is to the dizzy. Plug any other hoses or ports that are open. Ideally you should have a vacuum hose connected to the crankcase breather to help ventilate the crankcase

So, I guess I'll just remove the egr valve and the rest of the hoses, then cap the source.

Mark why would the condensor not be hooked up properly? Do you know who sells a replacement if it's faulty?

[So Cal Mark]

I have no idea why a PO would have connected it improperly. I doubt it's faulty, if it had failed I would think they would have removed it

[Fiat88]

Thanks for the help Mark and guys. Appreciate it!

I was searching the usual fiat suppliers and none seem to have condensers for 79 and up cars. http://stores.auto-ricambi.net/Categories.bok

Ok, so it's not a vital part of my ignition system then.

[So Cal Mark]

right, and since it's not connected and your car runs, that's proof you can run without it

If you can find one you should replace that intake manifold with an 1800 style. There is one on ebay now.

I was just in the garage trying to remove the egr valve but can't get to the second bolt holding it on.

I got the front bolt which I put the a red arrow to but can't get the one thats in the rear. Any tips?
