Please note its quite rare for an ignition coil to fail, infact in 8 years I have probably had less than 10 failed coils come through my workshop.

This might sound like an obvious question but are you making surte the thread of the sparkplug is touching part of the engine when testing for spark?

thanks mate, i've grabbed that one. i was checking the coil with the screw that goes into the end of the high tension lead up against the engine head fins.
do the modules fail at a higher rate than the coils, or is it the same?
i took the interrupt wires fully out of the carby to make sure that wasn't the issue (but made sure they didn't contact each other or the body)
