Yeah for the HSN ( high speed neddle) that sounds about right, for the LSN (low speed neddle)
have it flush with the end of the brass nut. And have the Idle neddle around 1.5mm open.
Now thats only the starting point so if your car is running like crap, dont stress.
From then on play around with the HSN (High speed neddle) screw it in just a little bit at a time.
and you will notice a world of differnts.
For the leak. If there is a leak (I dont think there is becuase it sounds like a tunning prob) you will
see little bubbles from the fuel line.......
Also check the slipper clutch.
And the glow plug is and OS#8
