I remember some of the same issues trying to get carburated 6 cylinder running smoothly.. In 1966 I bumped into Jim Littlehales who was the developer of the Lucas PI system. He told me how it worked, and that Triumph, (British Leyland Motor Corporation), would be fitting the system to a modified TR4A with a 6 cylinder engine fitted, plus other upgrades in 1967 the TR-5 was launched but the PI system was not reliable and did not pass emissions regulations in the USA, hence the return to de-tuned Stromberg fuelling on the exportTR-6's.
As always, thanks for sharing. Every once in awhile a person gets one of those jobs that makes them wonder if they really know what they are doing. Frustrating as all get out. However, perserverance pays off in the end and they have more experience under their belt. Also it makes for a great topic of conversation at the car shows etc... It's jobs like these that would almost make a person turn to the bottle and drink all the mental anguish away. LOL Personally, there was never any doubt that you were going to find the problem. Kudos Thanks and Cheers
Tr6 and spitfire need a heat shield between the exhaust manifold and the carburetors, the will start giving you trouble when the engine is hot, ask me how I know😂
The order is correct, that wasn't the problem. And yes, the distributor was installed on 180°, but the wires were installed in 180 too so that was OK. After I changed the spark plugs it ran much smoother.

Well that was frustrating for sure. I see you did use a Uni-Syn. Love the perseverance that you have.
It was the can of Stella that did the trick :)
Digging deep enough and you find the problem, good job. Now that you have the whole thing apart you will find more I'm sure.

Great work as always .
Absolute Triumph mastery!!
I liked that custom tool used in the first section to open the throttle. Harbor Freight or Snap On?
SNAPped tibia bONe :)
For me looks like the firing order (153624) are wrong, at the first start the engine was blocked be wrong firing. Or the distributor 180° twisted?

So now only the Stromberg Carbs have Constant Depression ! ;-)
