Definitely an 1981 model. smile Checked the bigger photo - yes 1981.

So - I will try that.

I disconnected the ignition module from the spark plug, removed it - and hung on to it - gave it a pull and didn't get a big jolt. No go.

So I will double check the kill wires too. Thanks for the tips.

Anyone got a spare (known working) ignition coil - just in case my checking proves correct?
