Engine Going Crazy
 

I have a Losi 810! I recently changed the sterring servo and now when i start the engine it goes wide open. Idk what i did to it. Before i start the car i make sure that the wheels and the throthle works and they do. Just when i start it up i have no controlle with the enigne. Any Ideas

is the battery fully charged???

So your steering and throttle servos work perfectly without the engine running as soon as you start the engine your throttle servo goes to wide open making your engine scream

What is it doing when you start the engine. Is the servo staying center with carb shut, or is it opening the carb? If the servo is fine it sounds like your idle gap is to big or you have the LSN to lean.

Sounds like your alignment on the throttle servo is wrong as neutral?

With both the electrics on take the airfilter off the engine and see how wide open the carb is, it should only have a tiny gap, roughly 1mm (roughly...) if it is huge, then you need to adjust your servo horn alignment or if there is only a tiny bit of adjustment needed adjust the trim on your remote.
