That's your decel valve. You also don't appear to have a flashback trap or hoses from your head vents (normal on a '75?).

Check the ports on the throttle body. On my '75, one of them was a dummy port and IIRC it was the one you have the vacuum advance tied into.

No head vents on '75 - '76.

The Throttle Body is that of a '73 (dual vac pipes for advance/retard). '74 up has a single vac tap.

What's with all the water hoses? Is this some trick hybrid cooled secret project ... ?

ok - found the main problem - one fat port on the plenum had no hose to it nor was it plugged - i plugged it and engine now runs fine - took it on a food shopping run with my son - he was impressed that this car has paint and an interior : ))))

also i removed decel valve.

more pics of drivers side port hole and passenger side port hole and decel valve before removal.

see my blog

thanks guys

The good Cap'n made a joke!

I've seen hoses like that collapse on themselves under vacuum.

I wouldn't remove the decel valve if I was you.
