Carb Screw Setting on MATRIX ?
Hi, i saw too many questions about the setting on the carb screws, and everybody talkin and talkin, and i got really confused, (NEWBIE 
)
So ... i ve made som pictures and i want somebody to tell me witch screw is for what is it doing when you move it clockwise, counter-clockwise,
i'm asking this, cause my car is running good, but it is always runing, even when i'm not pressing the throttle. i saw movies, all of the cars are stopped. mine is always runing.
maybe i have to fix the screw (i guess))
so here are the pictures
thankssssss[&:]

Check out [link=http://www.teamkinwald.net]www.teamkinwald.net[/link]. This site is run by professionals in the RC racing industry. This forum is just starting out, but it totally dedicated to the support of the CEN Racing products! By far the best place to be for CEN tips and advice. Not that RC universe is bad, but this site has more specific information about CEN products that you can only find from professionals.
They will provide you with the answers you are looking for if nobody here is able to help.
Sorry, I wish I knew the factory settings of the CEN carb. for you, but it more sounds like your throttle is set too high. Can you find a way to turn down the amount of throttle that the servo is giving the carb? This would not be done with the needles you pointed out in your picture. Instead, you would need to turn the setting down on your transmitter (if the transmitter is capable of this). Or you could try adjusting the servo linkage itself, to enable the carb to be closed more when the servo is at idle. If this all fails, try tightening the screw marked "D" about 1 tick on the clock.
Hope this helps!

A is your highspeed needle - turn it clockwise to lean(more power/hotter motor)
B is your midrange needle - this is to fine tune between HSN and LSN
C is your idlespeed screw - turn it clockwise to make it idle faster counter clockwise to make it idle slower. Sounds like you may need to go counter clockwise. You may need to adjust your Th-trim on the contoller too. pushing button left will lower idle / right will raise idle
D is your lowspeed needle - turn it clockwise to lean
Hope this helps some. If you need more answers post back. I'm not a master at tuning but my car runs pretty good.

Well I thought that needle "D" was the idle speed set screw.[&o] Shows how much I know about that engine.
Anyway, it's nice to see someone like BadSN95 can help clear up the issue.
Let us know if you can get that idle down.
