Hi all just wondering if there is a list or any info on the internet as to what readings i should get when testing ignition and lighting coils on Villiers engines. I have watched a few videos on you tube with all different readings so none the wiser.

Hi Darloman,
There's a very good reason why Villiers coil info is hard to find. Basically it's because good figures on the test bench often don't translate into good performance on the engine.
A coil on the brink will test well but under normal engine conditions of heat, vibration, dirt, a poor earth, etc, etc it will get unhappy. The usual symptom is poor hot starting. A sulky hot start on your first long ride of the summer is a classic story.
Villiers closed down the best part of half a century ago. Even the newest Villiers coil is ancient and suspect.
There is only one test for a Villiers coil. If in doubt, throw it out. Modern replacements are cheap and readily available.
I could go on. I like Villiers engines, crude, rude and dead reliable given half a chance.
Cheers,
