Just a thought, you haven't got electronic ignition? Sometimes it can cause similar symptoms.

Nope, no electronic stuff.

Think I’ve mentioned this before but,could be the coil breaking down under load/heat

Good thoughts, but looking at fuel filter when she shuts down, it's empty. So I'll check that first.
thanks!

Been giving this a lot of thought, searched around and asked car enthusiasts and think that i might have underpressure in the tank along the lines of what bugsymike thought about. The small hole in the gas cap isn't plugged but that might not be enough (which i thought it was and that that was the vent).

It could even be something else causing a lack of a good fuel supply.
Is it possible to make a temporary independent fuel supply directly to the carb to prove or disprove this as the problem.

I'm figuring out a way to do that safely, will be back with an update.
Thanks.

Re the front suspension. If the front bushes were ever loosened and retightened they are best pinched up at road height. If someone has tightened up the a arm bolt and lower spring bolts when the car is in the air it can Emily cause a difference in ride height from one side to annother.

Alternatively I would check that both rear springs are good and without cracks and also check both rear springs have the metal and rubber mounts at the top.
