Tried retarding the timing and had backfiring on the engine overrun, by the time I’d advanced the timing to stop the backfiring I was pretty much back where I started from.
Tried shorting out each plug individually and in each case plenty of sparks on the screwdriver and the engine died a little in each case, so I assume the plugs all ok.
Tried listening to the engine using a large screwdriver as a stethoscope, could not hear any knocking at the block or top head and neither on the crankcase at tickover or high revs, but she was standing still.
The dynamo and distributor gears sounded a bit rattley.
The carb does sound a bit sucky when I rev the engine and there is a distinct pause before the revs kick in.
But again driving her today she was pulling well once the timing was advanced back to where it was.
In ignorance I’m inclined to think it is electrical, but ignorance is blind!!
