[TR] Hoses to carbon canister for Triumphs similar to that, used on a TR6 (Sujit Roy)

[DAVID MASSEY]

 OK.  This makes more sense.  Thanks for the clarification.  My 71 TR6 had the two-port canister but I decided to fit an Anti-Run-On valve so I converted to later style (from a 73, I think) carbs, canister and hoses.  I had to fit up my own electrics to run the valve at shut-off but it works well.
I would think that aluminium (aluminum) heads would make the Anti-Run-On valve unnecessary.  The TR8 was not fitted with this system and my car never ever ever ever dieseled on shut-down.  Since aluminum is a much better conductor of heat these heads don't develop hot spots to the degree that cast iron does.

I think but am not sure that the '71 Stag originally came with a canister with 2 ports. But unfortunately, know one has confirmed. In some of the manuals and parts books, there are illustrations of the Stag having 2 2-port canisters.Stag no1 has a carburetor swap to a later Mk2 set. The Mk2 2 Stag has a 3-port canister. The ports on this type are vertical. I was able to find a 3 port canister from a junkyard. It came out of an MGB. THis canister didn't have a restrictor.Sujit

 Interesting.  The early TR6 (without Anti-Run-On valve) didn't have this restrictor.  Nor did it have the third port for the hoses that go to the top of the float chambers.  These were added to support the Anti-Run-On valve.  But if the Stag doesn't have the Anti-Run-On valve why did they use this canister?  I guess they used what was on the shelf at the time which is the part used on the TR6 at the time.

Thanks Edward. Yes the middle one to the valve cover. Small piece of plastic with a small hole in it.

There is a flow reducer bushing placed into one of the canister ports 
that is often missing.?? I don't remember which port but it is shown of 
the parts diagram.
