I can get the 185CDI to idle as low as 1200 on the stand. Haven't flown yet.
There's no need to get a super low idle, that's just asking for trouble.
Too many YS engine stoppages that have been blamed on the engine, have been caused by too low a idle.
On the ground, the engine must be able to idle reliably and steady for at least 30 - 40 seconds and then throttle up without any hesitation or burbling. If it can do that, then it shouldn't quit when going into spins.
Mine can idle for well over a minute and still throttle up immediately.
After you've been flying and ready to land, bring the idle back a few clicks. The engine will generally idle a bit faster once it is hot, so don't worry about it stopping. The idle speed needs to be just slow enough so that it will sit on the runway without moving.
