Thank you for getting back to me.
I do not know what the coil should test at. I have found that most of the coils I have tested in the past that tested good... were actually bad and didn't work
I even had a very expensive coil tester that we used to use and 9 out of 10 coils would test wrong.
I have found out that in most cases the only real way to test if a coil is good or bad is to replace the coils with a new coil.
I understand that this method seams like a "Backyard mechanic's way of fixing things, but in this particular instance, I feel it is the best way to go.
Make sure that you replace the diode that goes between the coils, too.
This diode causes a lot of trouble, sometimes.
I wish I had a better response for you, but in my 44 years in business owning a very large Lawn Mower Sales and Service business, I have not found a better way to test these ignition coils. Trying to test them seems to be a waste of time a lot of the time.
Please let me know what you finally fine the problem to be.
