Engine Idles Too High!

       Remove this ad - become a site supporter!
My engine idles way too high (too the point that it won't stop at all)... It's in a Hobby Craft Predator. I'm not 100% sure of all the adjustment screws on the carberator. And it's not the electronics - I took the throttle servo off and pushed the carb all the way in, but it still idled really high. HELP!

I'm no expert, but it kind of sounds like an air leak some where in the carb.

Well, the adjusment screws are pretty simple...
There will be either one or two.

The biggest one ti worry about right now is the High Speed Needle (HSN).
It is generally located close to the neck of the carberator..and sticks up a bit away from the carb. It sounds like it is running too lean. Turn it counter clockwise (to the left) with the engine running, and it should slow down slowly..only turn 1/8th of a turn at a time, because it can get real confusing if you turn too far too fast.

THis is a basic getting started guide from HPI..yes it's different, but all engiens work the same..give it a read, and let us know waht happens.


The next thing could be the idle adjustment screw..they are located similarly to the image on the HPI page, and it could just be to far open as well..not letting the engine slow down becasue the carb is just held open reagardless of what you do with the radio or pushing on the carb..

What part of the city are you in...maybe someone can help you out...

Thanks a lot. I wasn't sure which screw was which, but I just figured out which one was the idle adjustment. I'll have to take it out this weekend and retune it.
