Hit & Miss Engine Help Needed - Part 2

Really appreciate all the help and advice that I have had from - Thank You. I've put this second help video up as I'm still stuck getting a spark and the wiring has me really baffled. I've tried to point out in the video what is confusing me, so I hope I have explained it well enough to be able to obtain some help and advice.....as always super appreciated guys.

BillTodd:
The third (power v")  wire is for powered sensor such as hall effect (magnetic) or opto switch.

The voltage on the cdi says 4.25  so 4.5v from three AA should be ok . Do you have multimeter to check? What volts do you read on white contact? ( Should be between 0v and 4.5v)

If you don't get a spark now, I would suspect the cdi box .

Jim Dobson:
Thanks Bill, I have some more hours spare to muck around with the engine today.
Appreciate the input.

Jim Dobson:
Have Spark now !!!
Thanks again one and all, now have a really good spark using 4 x 1.5v AA batteries giving me 6v in total.
I can't get the engine to fire and start, any suggestions would be appreciated to get it firing.
I'm not 100% how to set the timing on these engines.
It has spark now, has fuel so what should I be looking for?
