Collection, Preservation and Display of Old Lawn Mowers
This is the sprocket and pin from my 1948 Atco lightweight Kickstarter mechanism
I assume it worn and not supposed to be that shape if so where can Get one please?
Maybe try the The old lawnmower company, as they break mowers for spares.
The shape of the sprocket looks normal. The lobes on the inside bear on the pawl to enable the starter to engage. The chamfered edge of the spring loaded pawl allows the sprocket to move backwards to return the starter pedal to the resting position. The bearing faces of the lobes may be a little worn but it is hard to tell from the photo. If it was engaging properly before it is probably ok.
Thanks sir chook
since the kickstart mechanism and piston were totally seized when I got it I have no way of knowing if it was working or not,but it's reassuring to know that it probably ok
I will reassemble it and give it a go
Almost my entire working life I have been involved in repairs and service to many and varied mechanical and electrical devices, and one thing I learnt very early was not to assume anything.
I also learnt that to be able to repair/rebuild/restore anything you first of all have to know how it works, if you don't know spend a bit of time studying the object and attempt to work it out, once you understand how it is supposed to operate the repair becomes much more simple.
Now to the question at hand I have no idea but I have 6 Atcos lined uo waiting for me to restore so I suppose one day I will be able to explain how the kick starter works. Good to see another Atco will be saved.
