Had a spare couple of hours today so I stripped the front of the engine and flywheel, removed the coil, condenser and points.
Points look good so they had a good clean then I went over the mower centre to get coil and condenser checked on jonathans machine, the coil came up good but the condenser came up duff.
happy to pay a fiver instead of 55 quid.
Hope to get it back together sometime this week
