When fully adjusted at the carb end, tick over is gill too low.
Idle mixture screw set at two and a half turns.
Will try and locate the left hand screw to raise the throttle body – that should work.
If the above doesn’t work then I’ll try the extra ferrule or adjuster.
Hope that it’s not the regulator, electrics are all a “bit foreign” to me.
Many thanks for your help.
