Just an update on the B&S.
A new set of points did the trick as it fired up first pull.
As my luck would have it though, fix one problem and another follows straight after.
What happens is this.
When the motor is running and you increase the revs, the pull start assy screams, I mean really, really screams (like a slipping fan belt on a car) and the starter cord begins to unwind about 20cm?
I sprayed it with a silicone spray and it did stop and was able to mow the front and back lawns without further problems. The cord also gradually retracted back to it's original position.
This is not a major worry atm, but I'm curious as to why it happened as it didn't do it before.
Merry Christmas to all.
