Thanks Max, I'll ask at my local mower shop to see if they have a load tester where they can test both coils under load to see if there is an issue with either of them.
The last time it cut out while mowing with the old coil in place I did check for spark and there was none, not at the coil, not at the spark plug and not with the kill wire disconnected.
Now that very same coil is working as it should with and without the kill wire connected.
The flywheel magnet is very strong, I stuck a 5/16' spanner to the magnet and it took 2 fingers to get it off. So that part is OK.
As for the fuel system, there is no fuel cut off that I can find and nothing mentioned in the parts manual.
I have a fuel tap installed in line.
I will try what you have suggested and see what happens.
Cheers
Steve
