Default Tuning engines

I just purchased a Volcano S30 with a sh.18 engines. I was doing the break in process and having a hard time tuning it. I was wondering what's the best way to tune my engine as for as the idle goes and the best adjustment to get full throttle and the truck not constanly rolling? Also the best way to adjust the break. Thanks for any help.

Default RE: Tuning engines

Put the truck up where you can work on it and the wheels spin freely.
First adjust the throttle trim so that at neurtal throttle the car idles fine and the brakes are off. Take off the air filter so you can see inside the carb for this step.
With the car running adjust the throttle trim until the car idles where you want it. (it will look like just a sliver of a gap where air gets in the carb)
If trimming the throttle setting doesnt work, you may need to remove the servo arm and adjust.
only after this is set you should worry about adjusting the idle screw on your carb.
pm me if your still having issues
