Just tested the coil and I'm getting 3.06 ohms of both the primary and secondary terminals. Is this the cause?

I have read excessive use of stainless steel causes high eddie currents in the body earth that can damage coil insulation

Have you got the green label Bosch one Mitch? I bought one of these genuine ones off of eBay - cheapest I could find:

gren or grey makes no difference
one is a longer service version gives higher spark voltage if you abuse your service intervals afaik

It's been mentioned that I should test the dizzy for an output signal as this triggers the coil? More info to confuse me, is this likely? It appears that I need a coil regardless but I don't want to pin all my hopes on it being a quick fix only to find it still won't run.

unless you tested it wrong it's faulty.
The chances of two faults at the same time is slim but possible.
