In the ys50st manual it says set the low speed idle needle 1 turn out, and the main needle valve 1.75 turns out! But then under break in it says run a little more rich for the first few flights! Should I just run 2-2.25 turns out for the first few flights on the main and 1.25-1.50 turns out on the idle..

Thanks!

1.5 on the idle, and 2 on the main should be fine. Any more than that, and you'll probably have a hell of a time keeping it running.

I can please 1 person a day.
It's NOT your day.
Tomorrow's not lookin good, either

Keep a close eye on your temps.

Better safe than sorry. I always run a gallon, or more, before I really push an engine.
