I adjusted my sons power valves today , idled down below 900 rpm's and shut engine off. Marked the cable spool and adjusted to 2.5 mm. I could turn the servo further by hand , my question is do you adjust them were the servo stops at low idle on its own ? Thanks for any help , Bigtriple

Yes. The servo will only open so far by itself and you will still be able to turn it by hand. Just adjust the valves when the motor has gone as far as it will on its own and you're all set.
