Tuning Tamiya Carb

[Wolfgang10]

Just bought a used Tamiya TG10-MK.1
Runs good but doesn't sound like what I'm hearing at the local track.
I keep reading about LSN, HSN, and idle set screw.
I know that LSN is the low speed needl, HSN is the high speed needle, and i know what the idle screw does. My questions is....where are the low and high speed needles? I know there is one piece that sticks outta the carb that i can adjust by twisting it, but i dunno if this is the HSN or the LSN. And i can't find any other adjustment.
Any help would be appreciated.
I need to bring down the idle so it doesn't speed off if i do not have the break on.

Lots of pics!

If you still have questions let us know!

Check the throttle trim on your transmitter and make sure it is zeroed out before looking to lower your idle.

Here's a pic with a three screw carb:

When i try to adjust the low speed needle as pictured, it seems to want to loosen the servo link. Is this normal?
