Carb Link Plate

Does anybody know what the link plate between the carbs (TKC1718) is supposed to do? Someone's suggested it's for mounting somthing to do with the aircon or summert.

It looks like it holds the carbs together so they do not wave about independently on the flexible mounts,or perhaps it is so that when the mount fails both carbs fall off together.The return spring finds it a convenient place to attach to on my car.I am sure there is a more useful/serious purpose,Steve..

The carbs are mounted on rubber if they were not rigidly linked the linkages between them would move around and possibly lock up as well as lead to imbalance.

TKC1718 indeed is for linking the carburettors.
UKC6168 is for the throttle return spring.

Funny I've been asking about this too this week.
I've been getting various parts plated in readiness for the rebuild of ACG 5, including the carb link plate. As two of my TR7s are sprint powered, the normal TR7 link plate is not big enough as the carbs sit further apart on the sprint manifold. So I thought I'd go on e bay and easily find a couple of spares and get them plated, as there would be plenty around that had come off a Dolomite sprint. To my surprise I noticed that the Dolomite sprint engine doesn't use the link plate, but the TR7 sprint does. Consequently I couldn't find any listed and the specialists don't seem to list this part either. Anyone know why the sprint TR7 has a link plate and the Dolomite sprint doesn't ?

Yes, it's because the All-Knowing, All-Seeing, All-Omniscient Gurus in the TR7 R&D department foresaw a time when the rubber carburetor mounts would split apart to fall off the manifold. The plate, TKC 718, was installed to keep them attached when the owner, who is traditionally responsible for completing the final 5% of the engineering work on the car, puts a couple of large hose clamps around it to keep everything in place.
That the plate is also useful for mounting other bits of hardware is entirely beside the point.
The Dolomite engineers lacked this ability to see into the future as they were on a different salary scale.

I asked about this on the Doly forum and someone there reckoned it's simply for the a/c solenoid, which the doly never needed. Sounds right, because it can't be to hold the carbs on when one of the rubbers splits if the Sprint or 1850 TC didn't need 'em. And, while it does do that, the only one I ever had fall apart (in driving the distance to the moon and back) was a remanufactured one from you know who.

On A/C cars the switch in the diagram senses full throttle (usually used in passing) and turns the A/C off for maximum power. It's on FI cars as well (but on the throttle assembly) with the solenoid which as stated ups the idle when A/C is on .

Interesting. I don't have one on my AC equipped 1976 car. No associated wiring either.

Don't have the link plate or don't have the solenoid?
