What's up everyone I'm having a little issue tuning this beast I've had nitro cars for a long time I completely understand tuning I just can't get my car to drop down to idle after a full speed run it stays idling a little high then after 5 to 8 seconds drops down to where it should be idling from my understanding I needed to lean it out a little more but I've done it till its to lean I've tried over and over it just doesn't work and I don't go crazy with the hsn it's tuned till that high pitched sound starts at full throttle basically as fast as it will go till I do t notice any more performance and is their any way to tell buy sound if that's to much or not enough

Lower the idle more and more... If the car wont run lean the bottom in.

This will also happen if you are too lean on top.

too lean on the bottom. You have a rich top end masking it.

Thanks guys I'll give it a try I was watching a couple videos of pro driver tuning and their cars drop right down to idle really nicely

Set your idle gap to .5-.7 mm. Then leave the idle screw alone. Set your top end so it is just a touch on the rich side to start when make full throttle pass. Then adjust your bottom end to get the idle right. Usually rpm hang is a result of being to lean on the top end.

Your engine will always tell you what it needs. Rpm hang or high rpm is a result of a lean condition, a rich condition will usually result in a low rpm situation. So you are most likely lean on top, and possibly a little rich on the bottom.

your problem is you own an orion engine. throw it out and get an os or nova.
