Thanks for the link Deejay, will look into a local dealer
.
I just did a run around to a heap of lawnmower parts suppliers to pick up a coil for the Briggs.
To no avail I might add, as it seems I have a early motor that has the ignition points.
I did however find a very helpful mechanic who suggested that it most probably isn't the coil that is my problem but the points and condenser which will be a very cheap repair if that is the case.
I have one ordered so will keep my fingers crossed.
