Thanks bigted.
Did some measurements today with a vernier and as far as I can tell the end of the jet go's into the tube in the body (?)
Some pic's:

This is one of the G4 body's.

This is the three jets from "G4's" on left and one from a Powertorque on right. They are all plain faced.

Sorry their not as sharp as I would have hoped.

Took a lot to get the Super started today, may be a combination of me putting to much oil in the crank, bore etc and the 2 stroke fuel getting a little old. Did however notice a not very convincing spark unless turned over pretty fast (i.e. drill). Comments?.
Once I used the drill she fired and ran very well. Warmed up at a fast idle for about 5 minutes, then ran through rev range a bit to max about half throttle, idled down then ran out of fuel after about 3 more minutes. Will get fresh fuel on Monday.
