I was wondering if anyone had an original vacuum hose setup in their 1972 TR6 and could share some pics, particularly from the adapter valve near the front of the engine and the radiator hose. I really need to make sure I don't have leaks and if it's not hooked up correctly, maybe that's why it's fluttering.

It seems my 72's vacuum hose from the distributor went straight to the left carb, and from looking at the Moss diagram it goes to the adapter valve instead (#72 in the Moss pic). You can see my setup below if you look hard. If that's the case, I do have some hose bends in stock if I need to hook that back up. Any help would be appreciated!

Do you have the rest of the Thermostatic Vacuum Switch (TVS) for the radiator hose ?
That would be 71 and 72.
The purpose of all that is to block the vacuum from hose "75" when the TVS waxstat senses the coolant temperature is excessive, thereby disabling the Vacuum RETARD when the engine is IDLING....that's going to make the engine IDLE faster, the radiator fan turn faster and the water pump turn faster which in combination may help the coolant cool down when the engine is IDLING.
That was feature only found on the 72, 73 and 74 TR6's
 
Sorry, that was a pic when I had the front disassembled. But yes, I have everything. I always the the hose from the vacuum went directly to the carb. However it doesn't look like it from the diagram.
 
That'll work. Only the 72, 73 and 74 were routed thru a TVS.
