You turn the idles screw...until it idles.

Trims dont matter TOO much, but when you start it, especially from a cold start, you can raise the trim on the car close to full trim and it makes it alot easier to start.When it does bring it back down.

you do know a idle screw just makes the carb go this way and stop to a other point?

my problem is that it idles too much that the car runs forward im trying to break in the car ,
and when i do get a good idle it's too low....

my throttle is like 98.9% open i would need a LITTLE small portion to get it 100%

those manufacturer settings were like 10x worse



I dunno really what to do


ahhhh the pain of nitros :P
once it runs your more than happy:P

sebhitman

yeah so i noticed , i can't have the carb fully opened , and also when it cranks back it's not enough closed even with trims

Im kinda confused!.

Get a new throttle return spring, its the one attached to your linkage on your throttle servo.Ive had one do that before as well.
If it idles too much, lower the idle.[&:]
Either by trims or the idle screw.
Is it broken in?

Disconnect the throttle linkage...........set the idle screw so the carb is open 1-1.5mm...........set throttle trim to mid point........turn on trans and receiver.........adjust linkage/servo horn so that when you connect the linkage to the carb it is neither pushing or pulling the carb open or closed.......thats it.
You have a manual? This is a new car and you are breaking the engine in?

sebhitman

yeah it'S new i did 1 tank on idle and i was about to do the street ones . but never got to do them

the car isn't right .... it's like impossible to do nothing on it , it's way too rich like i wanted to break it in but in the same time the damn Idle thing isn't right

also....

that rotostart is plain stupid it's scratching my rear spring like theres no tomorow + my dogbone im buying a pull start....



i think i have damaged my servo horn thing by taking it out too often because the break seems to be PUSHED BACK TOO MUCH when i break it isn't aligned with the throttle sometimes....


this is my 6th rs4 i have ever had never had such problem
also i dunno if thats a manufacturer problem but my CARB inside it..... theres a NOTCH that makes more air come in.... on one of the sides thats that a speacial feature for the t3.0 for more torque more air?
or is that a carb manufacturer problem....

I have no idea what you mean, pictures would be helpful.

Again, set the idle screw and throttle linkage as above.....set the brake rod/arm so when you brake it brakes.
Have you altered the other screws on the carb? If so put them back to what the manual says.
Do you have any friends with nitro cars or is there a hobby shop near? I am sure your troubles could be easily fixed with their help, explaining and understanding things over the internet is very hard.

I think ill rma the car ,

because I have found out the carb leaks.... and like i said theres something wrong with the car , it isn't just right


I had 6 of them in the past i never had so much trouble with anyone of them
ill try to take a pic of the carburator opening side notch.... youll see im pretty sure it aint supposed to be there
