I went for a nice ride on my Rapide today and found that pressing the recently fitted low-tension magneto cut-out caused the engine to drop down to one cylinder but kept idling.
Previously I had used the decompressor but as we know this is not a good thing so fitted the kill button.
I know the idle is a little fast(not a plonking steam engine) but nothing out of the ordinary.
The irony here is that usually these magnetos fail to spark. This Lucas KVF magneto was rebuilt 7,000 miles ago and failed at around 3,000 miles with loss of spark on one cylinder. This was diagnosed as the cam ring not being properly timed to the magnetic poles.
Does anyone have any suggestions as to what could be causing this mag to keep sparking on one cylinder when the LT is earthed?
