Ok. So i tried all the above an still no joy. I recorded my attempts and as you can see when i first try this is with the leads and dizzy what i think is the correct position as given by Nigel. Nothing. I then swap the 1 & 4 leads and the 2 & 3 leads and as you can hear a nice backfire.
So, my thinking is still that the timing is out somehow as my understanding of a backfire is the engine trying to run backwards because the ignition point is wrong??
After the video stopped i moved the leads round 1 place until i ended back at the beginning and the closest it got as a reasonable size backfire.
I am now at the limit of my understanding and skills. Got the club meet at the Malt Shovel tomorrow, but if anyone has and further ideas i am all ears, or if anyone likes tea, bacon/ sausage sandwiches and if free Saturday afternoon or anytime Sunday and wants to help out a fellow hoodie any help will be greatly appreciated.
Thanks
Steve
