Technical Weber DMTE 30/32 to Fiat uno 999 mk1

[chesh]

Hi all,
I've installed a Weber DMTE 30/32 on my 45 999 Uno instead the single carb, Punto 75 866 Camshaft + electrical fuel pump.

I am missing this unit (picture), Looks like someone took it off the bolts.
So I stay with just the output pipe which I don't know what to connect or block it. I don't know what it's purpose.

first run, everything was ok but it had a problem of going up to 2000 rpm and back to normal idle every 20 seconds.

I took the carburetor apart, cleaned it all and renew all gaskets + rubbers.
When starting the car now, engine revs to the limit without stop so I need to turn it off.

both butterflys of the carb working and it's not open on idle (even when accelerator cable is not attached).

There are 2 more electrical wires goes from the carb which are not connected to anything and I don't know what they do.

Anyone ever fitted this carb to 999 engine and can tell me what to connect to?
Also on the distributor, there's a diaphragm that I need to connect it's vacuum hose to somewhere? I guess on the back of the carb?

Hi, the red wire without the black tape looks to me like the fuel cutoff solenoid. And i think the vaccuum hose from the dizzy goes onto the small stub on the lower carb flange. Its part of the advance/retard for the timing.

Problem solved!
it seems that this acceleration pump was touching the adapter plate, and couldn't return to it's place.
