If you have vacuum and there is no effect on the engine then the retard
unit is most likely broken. These are available from the big three and
are fairly easy to change out.
They are held in with a "pin" through the dist casting. I'd suggest
getting a new pin also.
I see about 16 deg of change hose on to hose off.

I aquired my car with the vacuum lines stripped from the distributer
retard
unit. I installed new vac hoses. One leading from just behind the rear
carb
to the thermoswitch, and from the thermoswitch to the distibuter retard
port.
There is vacuum present at the end of the hose leading to the distributer
but hooking it to the port has no effect on the engine idle. Can someone
explain how the system works and typical problems? I've read that when
removing the vac line from the distributer port, the rpm should increase
from
800 to 1300. I beleive the problem I have with this system could be why
my
carb idle screws are backed almost off the springs to get and idle rpm of
850.
Thanks,
Jason, 72 tr6
