Do an LPG conversion. All the stuff about blocked jets stops being an issue. Lovely engine bay pics, all those lovely parts to salivate over...
It sounds to me like an air leak at idle. Usual symptoms are fine running at speed when the quantity of extra air won’t make a difference but at idle it significantly weakens the mix. A place worth checking is the brake servo. It draws its vacuum from the manifold and any leaks in the diaphragm will dilute the mixture. A simple test is to block off the pipe and see if matters improve.

After I've finished a cuppa I going out in Volvosaurus, 5 miles there, some work for a couple of hours, then 5 miles back. I report back later today. Not paid work I'm afraid!

If it's the latter that thing will be seriously mad, the Tesla itself is mad enough in terms of performance but in a Mini that only weighs a fraction of a Tesla that will be scarily quick!

This is very interesting, would like to know how this progresses. Some time ago I did a post here suggesting electric for the 340. I think it would make a great conversion. I have a Riley Elf Mini too, more space in the boot for batteries!

On another forum, someone started a thread about converting classics and asking for suggestions of suitable classics for EV conversion. My suggestion was the NSU Ro80. Assuming an intact example could be found that hadn't been converted to Mazda RX-7 power and that the original ****el engine was dead, fitting a motor in place would be a good conversion as the rotary engines had a noise not unlike an electric motor working hard. The possibilities are endless but i have a feeling that EVs will only be a "BandAid" on the environmental problems and a better, cleaner fuel will be found enabling the continued use of IC engines with little or no modification and much cleaner emissions. If there was an easy way to create Browns Gas aka HHO aka Heavy Hydrogen aka HOH and other simlar names, that would be near perfect but at present it takes more energy to split the water atoms into hydrogen and oxygen than would be derived from burning it. Meanwhile LPG is as near as we can get to that kind of cleanliness and only 50-60p/L. As you have a carb engine, it is much easier to fit than an injection engine and would be a good move IMHO.
