[TR] 1972 TR6 Overzealous At Idle

Is this a PI TR6?  Because a stock 72 TR6 with carbs shouldn't have a vacuum
advance ...

If it does have carbs, my guess would be that the vacuum retard is not
working, and the throttles are being held open by the linkage to the float
bowl vent valve.  On my 71 Stag, I was able to bend the vent linkage
adjustment enough to set the idle without the retard, but your 72 carbs may
be different in that area.
