When stops, does it have spark?
and, you can open float bowl of the carb to see is there any fuel.

It can be also something purely mechanical. I had wrongly reamed valve seats, when head heated up it jammed valves, and lost power.

When it cuts out if I pull the fuel pipe off and crank it it comes out so fuel must be getting to it .. There is a spark and the coils still cold .,, puzzled

Maybe a long shot but I had an intermittent occasional juddering. A mechanic friend of long experience suggested that there was a break in the wiring around the distributor which was only connecting when it felt like it and vice versa, something he remembered from his apprenticeship back in the day. I'd replaced everything like yourself to no avail, so in desperation I cut back the wiring in the coil/dissy area and extended it back with stronger wire. It worked - my intermittent occasional juddering has never returned.

My mechanic friend of long experience now maintains the Angels cars but his earthy advice lives on in my Mini.

I've tryed another wiring loom from dizzy to Coil still same it's in to be looked at and fixed and tuned next week so they should find the issue as I've lost ideas now . Need a fresh brain to probably find something ive missed , thanks for all suggestions but like all minis they can be head aches at times just can't wait to have it solved and be using it

I started it today it cut out then refused to start but as soon as I pulled fuel pipe off carb and blocked it and then it started , the cars on a mechanical fuel pump so surely it can't be recieving to much fuel

Needle valve got dirt behind it or worn allowing the engine to flood

[spritey]

The needle valve which has a small filter under? I've had carb off cleaned it and replaced it

Possibly daft suggestions but could the choke be getting stuck or there be some sort of mixture problem ? Another idea would be to check to make sure the fuel tank is vented properly. Try running it with the cap off.

I will try that today Steve , it's in for setting up and tuning tomorrow just wanted try and get it running as its bugging me

Update ! It was the breathers and needed engine set up the carb didn't have the breather pipe to the breathers on the engine .

Aswell as manifold leaks so new filters on between carb and manifold
