Check your battery and earth straps. It sounds very much like the battery strap has been touching the exhaust, has melted the outer sheath and the engine is now earthing itself through the exhaust system.

or it's just running extreemely lean !

Oooor, you've inadvertedly fitted an F1 engine to your car.

That would be clumsy!

Could be an exhaust valve thing check your tappets 'n get the compression tester out if you can lay your hands on one.

Good Lord , what has he got as a battery ? If the earth was glowing red hot , then wouldn't the positive feed as well ?

I would tend to look at extremely retarded timing , plug leads swapped or exhaust valves hanging open.

I suppose it depends on the material the current is flowing through?

retarded timing......

[dklawson]

Check the static timing but it sounds like a way lean fuel/air mix to me.

[mk3 Cooper S]

Yes either very lean or very retarded timing.

Is it better if you pull out the choke giving you a richer mixture?
