I'm in a bit of a pickle, and I need some advice. My S is struggling to start. It will strike, and make a quick burst to perhaps 2000 RPM, before it collapses and stops. Today, it will do so perhaps 3 times before it stalls completely.
A video of the car struggling to start is in the link:

https://photos.app.goo.gl/8NU8hfpcrr3cjhJu9To this date I have exchanged every part of
- the ignition (cap, rotor, leads, points module, spark plugs and coil) and monitored the supply for consistent 12 volts through start (yes).
- I have looked for induction leaks, and found none, including by blocking off the PCV and Booster.
- Regardles I pulled the carbs and manifold down, and rebuilt, including manifold takeoffs. The jets are clear, and bowls have the right levels of fuel, and the gaskets are all new.
- The dizzy curve is locked, and there is an accuspark blackbox. I have removed the box and connected the dizzy straight to the coil. No change. I even took the opportunity to try out the new stealth mk3, to see if it was the old stealth mk1 that was the problem.
- I've drained and replaced the fuel, clearing the lines to ensure a fresh batch.
- Compression is great, and it seems to fire on all four cylinders when it does kick.
I'm pretty happy ticking along with it, but I'm out of ideas to chase. I'd appreciate ideas, and will happily retest if I need to.
cheers
Mick
