Saw this locally and put in a bid, weak moment. I was really hoping by the time the auction ended it would top my £8 bid, alas...

It's all there and includes grass box, there is no spark, I will run through the checks but if experience serves it could well be the coil. 

If it's a 2 pole coil/flywheel combi then looking at £60 for a new one, if its 3 pole then about £30 for replacement coil. Either of which is worth more than the mower working...

Connections are fine, 2 pole coil, minimum £60, inlet stuck open which is no big deal but think I will walk away from this one.

Will keep the carb, exhaust, tank, recoil & cover and probably weigh the rest in :-(

Just out of interest (??) inspect tha back of the coil and see whether the hard shell has separated from the potting material. If so, you could treat the coil to a week of gentle warmth in the airing cupboard (next to the welding rods) and see if it regains its spark. If it does it's unlikely to last but you never know. However, looking at the amount of "crud" around the back of the flywheel its possible that the coil has been well cooked!

Should just add that the two and tree pole coils each require their own specific flywheels.

Well it's a shot to nothing so giving that a try, although there are no visable cracks, in fact its in rather good nick externally - which is no guarantee of it being ok.

Its now snuggled up on a box of 6013 in the airing cupboard, have cleaned off any rust and inside of flywheel, will retry next weekend.

Indeed, hence I am tied to the more expensive 2 pole coil, I have a spare f/wheel but that 2 pole as well....

EDIT -  After 5 hours or so warming up in the airing cupboard, 2 cracks running the length of the flat side of the shell are clearly visible which were invisible when stone cold! If it does fire after a weeks dehydration I may JB those..

Well it was worth a go but unfortunately still no spark after a week in the airing cupboard.

The coil casing cracks opened up a fair bit, wether this is due to swelling of oxidised windings or just that the plastic distorted I don't know, but I may cut it down the middle out of interest

That's a shame Chris, certainly worth a try! If you do decide to put it under the knife I'd be interested to see the internals :)
