You need to turn the idle stop screw out about half a turn and start leaning out the high and low speed needles. The engine is spitting fuel because it's running super rich which helps wash out little particles that might develop in the engine during the break in process. Now that you have a few tanks through the engine, you probably want to start leaning out either the high speed needle or the low speed needle 1/8th of turn for a tank of fuel. And each consecutive tank, you lean it 1/8th of a turn again.

You car should have some sort of instructions on engine break-in in the manual.

There's a whole bunch of videos on youtube on how to break in an engine as well.

Well as for the fuel spitting out your just running wayyyyy to rich. Try leaning the engine out by turning the high speed needle clockwise. But only lean it out a quarter turn at a time. Now leaning the engine out will speed up the idle. So first check your trim on the remote and make sure it's not set high. If not you'll have to turn down the idle by turning the idle srew counter clockwise until the engine sounds nornal and stops moving forward on ya. Hope this helps.

Thanks

RE: Is this normal
 

That's really werid. Are you sure it was the idle screw you used? Now how much did you turn the idle screw counter clockwise?

RE: Is this normal
 

i did it but when i go to rev my engine it revs but stays to the rpm and go to that speed and only stops when i put the brakes on
the throttle is sticking not on the contrler but on the car what do i do ?

RE: Is this normal
 

Is the car new cause if it's used the servo could be very tired.

RE: Is this normal
 

it brand new 2 days out of the box

RE: Is this normal
 

hmmm, that is really werid... I'm out of ideas

RE: Is this normal
 

oh ohhh maybe the metal rod that comes from the servo arm has got somethink to do with it ?

RE: Is this normal
 

Oh yes. Is there alot of play in the rod? It should be nice and tight.

RE: Is this normal
 

abit yeah

RE: Is this normal
 

Well it's fine if there's a bit of play but not much.

RE: Is this normal
 

then why is the throttle sticky

RE: Is this normal
 

I am offically out of ideas. It could be you have a faulty carb.

RE: Is this normal
 

going back to the servo arm its bent i dont think its ment to be like that would this have a affect on it?

RE: Is this normal
 

Yes that could most certainly have an efect. Can you take a pic and post it?
