MG TD TF 1500 - separation in inlet manifold

Hello,

Does anyone know of a kind of separation in the connecting pipe of an XPAG TD inlet manifold?

I seem to remember, that there was one in the manifold of my '52TD when I restored it some 30 years ago and I wonder if it is original and why it is there.

Regards

Eric, see the info about the restrictor in the old thread. Bud

OK Bud, Thank you.
Which thread is it?

It's called Intake resistor Bud

OK, "intake resistor" does not exist, but I suppose, that you mean "intake restrictor" but that thread has been removed.

What do you need to know? The restrictor consisted of a vertical disk shaped plate held in place by a screw at the bottom center of the intake manifold used to keep air/fuel mixture from being sent to the wrong cylinders. If the screw holding the restrictor falls out - which is not uncommon, a severe vacuum leak ensues with attendant rough running.

Eric, I gave it the wrong name. It's Intake restrictor that's in the present list. Sorry. Bud
