Hi Norm ,
I once had to change the coil 4 times until I found a good one ,when you don't have a coil load tester it's worth
taking a coil from a mower that you have just run a minute ago to save time , it's the same thing with a spark plug I'd rather
use a plug that runs in another mower just in case the new plug doesn't work .
I've had some run then next time won't start and when I check the magnet on the flywheel they have lost
their magnetism.
sometimes I put starter fluid in the spark plug hole instead of the carby as that will tell if you have a valve or cam problem
or a flooding problem.
I usually start with a compression tester and do the easiest things first then later on check the flywheel key just in case the
flywheel has moved a lot and the motor has no kick back.
Cheers
max.
