NOW, what Traxxas says about the LSN:
Note how the LSN is flush with the BODY.
My Maxx (I got it used) came with two carbs, and both were set very close to the bottom picture. When I set mine according to the top photo, the thing spits gas out the exhaust like nobody's business...
My instinct / gut feeling has always been to set it via the second photo, although I had no reason to believe so. Now I found that photo, and have a tingling feeling the top photo might be misleading?
Do any of the gurus here have opinions on this situation?

Thanks![/QUOTE]

I'm NO guru (as I've got the manual infront of me) and I do have a T-MAXX

,GO with the lower foto (AS ABOVE) thats the right one IF you have the TRX2.5 ingine. . .
the throttle arm (part#5243) can be moved or changed, so you set your L.S.N
flush with the inside as seen in the foto.
Hope this helps you.
Regards.
