Hi Frode,
Read page 676 ad 677 of this thread for details.
Basicaly if the needle is still in the receiver jet a WOT you have the long LSN. If the needle comes out of the receiver jet at WOT (even by a small amount) you have the short needle LSN. See pics below for actual physical difference. Long needle on the left, short needle on the right.
Short LSN tunes like most other carbs. The long LSN tunes a little different.
See the Tech Tips page on my web site
www.go-racing.co.nz for tuning details on the long needle carb.
If your motor came from Taiwan it should have the factory standard long needle.
Go had a .12 motor in the wings last year. I am assuming it is still under development. Mark at Massive Mods will be able to shed more light on that.
