yes that is correct, just remember, adjust in 1/8th turn increments only. adjust 1/8, then see how it works, repeat as nesicary

thanks!
is there a general rule for a stock setting? I have the high speed settings both at 4 turns out and that is working pretty good but I want to tune both motors in at idle.

Do you know what kind of motor it is? or if it's stock, you can go to the web page of the company that made the truck, and download the manual. Mine is usually around 3 turns back. But, remember, no smoke = bad! if you spit or drop a few drops of water on the head, it shouldnt sizzle away right off the bad, it should stay for about five seconds, after you have just run the truck and heated it up. If it stays longer, go a bit leaner, and shorter, richer.

that is the trx 2.5 motor that comes stock with the tmaxx..
what you have labeled as the low speed needle is actually your idle screw.
the low speed needle is on the other side.

this link should get you going..

Default are u sure its LSN?

are you sure its LSN?

i thinks it is the idle needle the needle that control the carburator drum/slide opening....

correct me if i am wrong...

coz to me LSN located at the end of the 'accordian' thing.... connected to the carb drum/slide not the at side....

hmmmmmmmmmm
