There is only a spring between carb and poti. Attached some photos of the tbi.Let me know if you need more pictures.
Sorry it's been a while since I last posted, been working on my other Mini getting it MOT'd. I'm now back on my 94 Cooper SPi. I have an update, I replaced the thermostat, the vacuum seal to the brake master cylinder and the whole inlet manifold, throttle body and air filter with one I sourced from FB marketplace.
The engine now starts and idles great but will not accelerate. It's almost impossible to drive, you have to slowly increase the engine revs and pull the clutch out to get it to move, even then it's like a galloping horse with no power.
I took a MEMS capture from cold and have attached it here, I just wondered if you could see anything obvious in the data?
