If your frequency valve is buzzing and if you press the full load throttle microswitch on (the small grey switch) and this makes the dwell change from 45 deg to 54 deg, but shorting the oxygen sensor ecu input wire causes no change, then the fuel ecu is faulty.

Try another ecu.

Chances are that the quad operation amplifier chip LM2902N has failed, so will need resoldering, but I can't guarantee this.

Good luck

Ok, then I need to find a volunteer to borrow his ECU, that won't be an easy task
I don't think we have this one to the club but only the ignition ECU.
On the other hand, I can try to change the chip someday...

.........

I can bench test it for you or send you a known working tested one to try, ........

[Domi]

Raphael from France has one for spare and offering me to send it to me to give it a try.
It will be cheaper to test it this way than send it in the UK.
Nevertheless, appreciated your offer
I'll let you know

[Admin-bloke]

Ok, My offer is still there if need be.

Bonne Chance

Is the brown lead going to the coolant bottle metal bracket in the video domi ?
Dunno if that's a good earth point , try just touching the brown lead to the engine block itself, like the cam cover , to make sure it's a good earth

Cheers

On closer look It's looks like your metal bracket for cooling bottle has an earth going to it , apologies if that is the case ,
But still might be worth earthing it somewhere else like the engine itself ,just to be sure

Ok, My offer is still there if need be.

Bonne Chance

Appreciated, thank you so much

Worth a try, you're right

Decided to go for a ride to see how my idle goes, was fine all the week without moving.
Unfortunately, after a few minutes driving something else happened...
I hear a loud noise on the front and was almost unable to move the steering wheels.
Finally I pull over on the road to see any damage.
I lost a nut on my lower arms which were brand new from Midwest.
Unfortunately, the nut isn't drilled and is just a lock-nut which moved away.
I checked the other side and is almost unscrew too, amazing!
So, like I wasn't too far away from home, my wife brought me some tool to repair the car.
I think it damage the steering rack (which was brand new from Ed) like I was unable to turn the steering wheels properly.
Anyway, needless to say I'm a little bit disappointed. I spent two years working on the car and now I'm a little bit tired.
Here are a few pictures...
