Ok thanks

Hi the wire from the coil to the points isn’t long enough. Do have to use a specific wire or can I use a strand from normal three core cable?

I think I am going to change the condenser it was the only part of the ignition I didn’t change during the rebuild.

Ok thanks

It’s a new plug cap and the tester flashes when it’s connected from plug cap to earth. It’s as if the spark is not strong enough to jump the spark plug gap. Could it be the condenser?

Plug cap

I’ve used 2 brand new plugs and the gap is correct. It’s a mystery to me

That’s the point I’m getting a great spark to earth without the plug attached but nothing when the plug is attached

I’ve tried that Charlie but there is no or very intermittent spark but if I just connect the spark tester to the plug cap and the spark tester direct to earth without the plug the light flashers as it should

Thanks for that Charlie. Does anyone know the equivalent gr8 the Lodge BN?

It’s a Mk12 villiers it had an NGK B-4H but I have since been told that plug will run too hot.

The spark plug that I removed is a 14mms thread and I now know the CB3 is an 18mms but I now wonder why the manuals for the engine and tiller state the plug as CB3

Sorry that should read CB3 spark plug😏

Missed a page

Thanks Charlie all up and running now. This is the carb that was fitted. By the way can I order another transfer please.
