Finally got a day that I could spend in the garage tinkering with the mowers.
Got the Qualcast up and running and finally got the mixture about right, new chains on and it mowed!
Wife wasn't happy when I mowed the emerging crocuses though!
Thought I'd have a go at the Atco lightweight I also have but had less joy.
There was no spark so checked the coil, open circuit, same with one of the spare engines I had but then a glimmer of hope when the last spare had a resistance of around 2k ohms.
I guessed that this was probably a bit low though.
Pulled the engine and swapped the coil over, still no spark, points set all ok, no spark but if I hold the ht lead there is a slight jolt but nothing like it should be like.
I'm assuming that 2k ohms probably means that the coil has a short somewhere in it?
So I'm looking for a coil for the Atco, if anyone has one they'd be happy to part with I do have a few spares I would swap.
Cheers and happy Mowing
