thanks for the assistance chaps. Much appreciated. Certainly fuel is being drawn to the carb. I've covered the intake with my thumb ensuring closure and flipped the prop over, (Without the ignition on!!) and scored a wet thumb. So fuel is being drawn.
But on pulling the spark plug, it appears dry. So I'm assuming nothing is going through to the engine itself.
With regard to DarZeelon,
I believe the sensor is mounted correctly, I dont believe it can be mounted any other way. Although the sensor doesnt cover the aluminium coloured dot on the drive washer. Should it?
All other wiring is correct.
