Ok I got my car tuned somewhat properly... BUT for some reason when I brake the car stops and when I release the brakes the car accelerates quickly and neutralizes.. something it even moves just a bit... ANY QUESTIONS HOW DO I FIX THIS??

Thanks

Not trying to trash your thread, but thats what the brakes are for... stopping. When you let off the car is supposed to...accelerate?

You might just have small problem with your throttle trim if it just jumps from full brake to WOT or the likes. Try diffirent adjustments to the servo trim and see if you can get better results before adjusting you LSN just to be safe.

Is this a joke????
 
see that set screw (ahh poop... whats it called again? The cylinder shaped stopper with the small screw inside) on the end of your throttle linkage? (the closest to the outside of the car). Move that outward a little more so that when you brake, and let off it is barely not touching the stopper. (you dont want too much space in between) That will make it so that you dont accelerate when you let off the brake.

Tweak, he meant that the engine was actually giving throttle when he let off the brake/gas, not gliding at idle.

I'm thinking by stopping, he means the engine dies, right? Sounds to me you have two issues here.

One, when applying the brakes and the engine dies, sounds to me the idle set screw is backed out too far, allowing the carn to close completely. You need to set this screw so that, when you apply the brake, you maintain about a 1 mm opening for the carb. Easiest way to do this is, pull the air filter off and look down the throat of the carb. Turn the RX and TX on. Carb should be open just about 1 mm now. Now, give it brake. If the carb closes, you need to turn the idle screw clock wise. Open the throttle (i.e.give it gas), turn the idel screw a time or two, then give it brake. Repeat this process until you maintain a 1 mm opening in the carb when applying the brake.

As for it jumping from brake to WOT, could be two immediate things. One, the trim on your throttle channel is cranked too high or two, you need to center your servo. If it's the trim, just crank it down. Ideally, you want your trim as close to "0" as possible, that way you have the room to make adjustments throughout the day. If the servo needs centered, that's easy to. Turn on the RX and TX and make sure the trims are set to "0" or neutral. Now, pull the servo horns off then reattach them as they should be (check your manual on how they should look with no input and 0 trim). Screw them back on and you should be set! I typically center my servos every couple of outings, but that's just me!

Hope this helps!
 
I got most of the brake issues solved.... my only issue now is that it cuts when I give it full throttle... I can't get the LSN back to factory for some reason.... HOW COULD I? Cause it looks kinda like aligned perfect but the car doesn't ride right? Thanks

The LSN is NOT causing your engine to die at WOT. You have the HSN too lean. Crank it back one tick on the clock I mentioned until you get it dialed in.

Think it through logically. LSN stands for Low Speed Needle, right? HSN stands for High Speed Needle, correct? If the problem occurs while going to High Speed, what needle should you focus on? I'm not sure why you can't get the LSN to factory, do you just not know what that setting is? You've yet to post what engine is on there, so that would help tremendously if you could share that little nugget of information.

Keep trying, you'll get it.
 
find the factory settings,reset back to them,that way you can start from fresh.
 
Sounds to me as though your LSN is out of tune. It could be to rich and floods the carb too fast. Check and let us know
 
How much blue smoke,and unburnt fuel is coming outta your exhaust when you do that.
 
athe smoke is very BLUE and it smokes like a chimmeni...

Monkey I know what flush means but that screw barely moves when is turned so it's difficult to align it honeslty...

thanks
 
does it smoke like a chimmeni at idle,how long can you idle before it dies,how long can you go at low speed's before you shut down?
 
Just busting your chops, man. I think Jon2 has the right idea, though. Your first post led me to believe if you were at half throttle and you jumped on it, it died, not from idle.

Set your HSN to flush, then set your LSN to flush, then one tick on the clock to the right. If you REALLY have to wrench to turn the LSN needle STOP! That means it's at the bottom and is closed. A good way to tell if you have your LSN set right is, once you've gotten it running, pinch the fuel line going to the carb. The engine should rev up then die in about 5 seconds. That tells you you've gotten the LSN set right. From that point, it's typically the HSN.

Good luck, man! Just be patient, you'll get it running good!
 
Well guys..... yea it's working excellent. I will try to regulate it a tad on the HSN but other than that it's running very sweet... THANKS TO ALL for the great help
