Yes Doc, but yours start and stop within an hour and the sun is back out and it's warm again. We're in day three with rain showers, no sunshine, low 50's temps and more of the same tomorrow.
BUT...........Monday, when we all go back to work, will be sunny and warm!!

Have you been peeking at my old tri-carb conversion? I had to remove those due to constant binding issues both hot and cold. You didn't read into the updates with the Ratco.
I spent over 10 days and countless hours tweaking those to try to get it right and with the individual manifolds and rates of expansion, you need the flex shafts even more.
They may possibly work on a solid manifold, like the stock unit, but not with the GoodParts setup.

The tri-carb throttle shaft issue with GoodParts manifold is it needs an amount of "flexibility" t'wixt the shafts. I been watchin' the threads and wonderin' about "solutions" to it. Anything I come up with would be certainly elegant... but NOT as simple as the combo spring clips/clamps Paul has now. Don't "re-invent the wheel" here!

Hi Al: I was intrigued by Paul's solid throttle shaft connectors , for possible use on my triple ZS system, but didn't pursue it when Paul reported the problems he had.
Shortly thereafter, Randall posted a link to a company that makes a lot of small mechanical parts, in response to an inquiry unrelated to carbs. Here's the link:
https://sdp-si.com/eStore/Direct.asp?GroupID=200
I ordered Part No. A5Z 7-11010
It has a 5/16 bore to fit the throttle shafts, and is about 1.18" in length. Rigid, but tolerated some angular and parallel misalignment.
I had a problem with the length of my throttle shafts, so this was an excellent solution for me. If your throttle shafts almost meet, it may be too long w/o shortening one of the shafts.
I like them much better than the folded spring couplers.

Very interesting. So the body is a polyurethane with steel collars? Good concept and with the heat, it may allow enough flex to work well.
My big problem with the solids was that when it was warmed up, I could get everything aligned and set perfectly and the idle was at 850 RPM. Then after the car cooled it would stick at 2,000RPM, so I'd slightly realign the carbs and all was well until warm up and I'd have to start all over again.
Again, I gave it a lot of time and effort and when I thought I had it, a problem would arise, so I bagged the effort and chalked it up to experience. Having a throttle that will stick at times is not part of my planned performance from my car.
Like I said, with a solid manifold that won't flex like three individual units, these would be great. I was all hung up on having the neat appearance of the solids, but I don't think that I've ever looked at the folded couplers again, since I installed them.
For the hassle and aggravation involved, I guess that I just lost interest and moved on to other projects. Which may or may not have been a good thing.....

The solution is Webers, you will not find any needles that work for the ZS, Jag included. ZS's ain't going to do what you want to do. Either Webers or FI. Why spoil your fun? You already know it, listen to that voice inside of you telling you this, don't give in to the dark side of the force.

Searcher,
You keep talking like that and I'm going to have Tony lock this thread!!!! FI, maybe, Weber's, never!!!
My B1AF needles work just fine and tweaking the carbs with my A/F Ratio meter tunes them right in.
It's funny to remember a show last fall with a guy next to me with Weber's. He pulled in and was revving the car and making all sorts of noises as I just sat there minding my own business. Everyone around oohed and ahhed the Weber's and in all fairness, they do look MEAN.
So after about 20 minutes, along comes a well known guy who owns a local LBC repair shop. Now the show is getting packed and I'm getting a lot of attention and so is the Weber car. Someone decides to ask us to start the cars up and listen to the engines. So I reach in from outside, turn the key and it fires right up and idles nicely at 850. I rev the engine a bit from under the hood and everyone is smiling, so I shut it down.
No he has to start his and what a disaster. It won't start for two minutes and when it does it won't idle. Now I know why all of the noise was made pulling in. I felt bad and he was embarrassed. Turns out the local guy was on his way over to help him tune the carbs after hearing him pull in. He knew that it wasn't running right and spent nearly an hour getting it to idle.
After the mechanic finally got it to idle and made an appointment to re-jet the Weber's and fix the mess, he grinned at me and said "Smart move buddy!" as he walked back to his display.
That was enough for me about Weber's on a street car. I do believe that if you are racing, they are the best, so I know their value. I just don't think that I need another $2,000 for those issues.
Now Alan's fuel injection is another story. A local guy here in RI is fuel injecting his TR6 with a package out of Maine, as we speak and I will be seeing that soon, so more to come about that. I believe that he is doing the throttle body conversion.

Paul,
Is the RI guy doing Rick Patton's https://www.pattonmachine.com/ TBI conversion? If so, it's a nifty package, easy to install and the car runs great after. Nothing for Tri-carbs yet, but it's in his future plans. The next time you're driving through Wallingford, give me a call and I'll show you the TBI set up.

#6,
I don't know of any triple SU available to fit the GP manifolds, or I probably would have gone that route when I did the swap.
BobbyD in CT has done the Patton throttle body swap and Elysium in RI is in the process of doing it now. IF and I mean IF, I ever decide to change something and I'm not because I'm perfectly happy with my triple ZS setup, I would probably lean towards the TBI. If no one has come up with any SU swap out by now for this, I doubt they ever will.
Now if someone designs a cast aluminum manifold that is one piece and incorporates a triple TBI setup that will bolt on and off and is tunable (programmable) for varied street and performance engines...........now that might be something worth looking into.
I don't know who is worse at stirring this FI stuff up, Alan or Searcher.
