If it's the AE/TTR .15 that comes stock on the RTR, here's how to set it. First, set the idle stop screw (the little one next to the carb opening) so that there's a 1mm opening in the carb inlet when the throttle is closed.
Then set the HSN. Turn it clockwise until you just feel it hit the bottom. Don't tighten as you'll distort the needle seat and toast the HSN assembly. Then turn it counterclockwise 2.5 turns out.
To set the LSN, hold the carb arm closed. Turn the LSN in until it just hits (same as the HSN). Then turn it out 2 to 2.5 turns. Should be all set. Also, as recommended in your other thread, you really may want to take an evening and quickly clean out the engine. If you're seeing grime or sludge in there, there also may be some debris in the needle assemblies that will restrict fuel from getting into the engine.
