... I found that my ignition is massively retarded (30 degrees ish) ...
Dear smithjames0 ,
please note that it is impossible to have ignition retarded compared to the top dead centre. This would mean that you would have a spark when the piston has left the top dead centre and is already going back to the bottom dead centre. You need to have a spark before the piston reaches the top dead centre. I can imagine that you took the measure of anticipation of ignition (not retarding) and this was about 30°. In my opinion this is too much. I would turn the stator clockwise until you set it up to 25°.
Once you were able to set it at 25° you should set the contact breaker points at a maxcimum distance of 0.4 mm as MarioNYC already told you. Double check the anticipation angle and you should be ok.
Good luck

Hi,
It seems like I got mixed up
The timing is correct
I also check the wiring on the back of the magneto, all looks to be ok.
One interesting thing I did spot was when the engine is turned over, if the green magneto wire is connected to the coil I get voltage through the grey magneto wire. But when the grey wire is connected to the coil and the green wire to the distribution block (wired correctly) I don't get any voltage out the grey wire
Regards

We’ve made progress this afternoon
turns out the fuel line was blocked, now the ape starts first time
However I still have not sorted the issue with the green and grey wires from the magneto.
How do I measure the voltage from the magneto? I’ve tried using AC setting on my multimeter but it’s just a blur of numbers even on the highest range.
Regards
James
