Put the head back on the ruby today after a clean up of the valves and head (& having a look) - It's not running with any gusto at all. Not developing any power and dies after a while of unattended running. Does not seem to rev much, needs a bit of choke to tickover more satisfactorily. I was about to hop in to do a test run when it virtually died climbing a small slope out of the garage.
I suspect an electrical fault at the moment - the ignition cutout seems to make to difference - not least because the car starts and runs without the cutout key inserted...
I've swapped out the condenser and the coil, the points are ok and no cracks in the dizzy cap. New "hot" spark plugs (bit sooty when inspected). New HT leads fitted and a good spark I think. Compression tested and found to be good. Tappets freshly adjusted and all moving freely.
Currently I'm down to:
a) air leak in the manifold
b) dizzy rotor arm?
c) dizzy is too far advance/retarded
d) the car is possessed and needs exorcism.
I'm about out of ideas here so all suggestions welcome!
