Thanks for that Grumpy, it's a fair call on being abrasive on the module.
The reason why i asked is yesterday i was trying to get a powertorque with a weak spark to fire up. I removed the engine off the deck and noticed a very small air gap. I reset the gap to the specified 0.25mm and still no improvement. Swapped the coil over with a good used one and exactly the same result. At this point i'm thinking "what the..". There was no module to change as this was a later model powertorque.
Today i decided to tackle it again and opted to swap out the flywheel, with great success, it fired up on the first pull.
So 2 things were learnt: 1) A smaller air gap has minimal effect on spark, 2) Flywheels do occasionally stop generating enough magnetic current to produce a decent spark.
