2072 ignition coil
Have an 2072 with a Kohler repower CH730-0097 engine in it. looks to be a 2004 year model. Had to replace the rear seal in it, so while out (and had to remove ignition coils anyway) I thought I would ohm the coils (reason being, after mowing for a while and shut it off, it backfires and wants to stay running, then finally shuts off) one coil reads 8.97k ohms to ground and the other reads nothing. I believe the one reading nothing, might be bad. Is there a correct way to ohm them or do you have to have connected back up and check it at the spark plug with a tester.
Thanks for any input Randy

 t would seem that if one of the coils is bad, it would run real rough.

well put engine back in and checked each plug and it had spark. so i guess all is well, runs good, except it still backfires when you back off of the throttle. Any one know why it still does this?

Usually an exhaust backfire on deceleration is because of an over-rich fuel mixture.
Other possibilities are: -leak in the exhaust that lets air in -vacuum leak -exhaust valve not seating -timing off (not likely on a magneto ignition, but possible) More than likely, too rich on the carb.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.
MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
