If you’re getting smooth idle at 1600 rpm and = sometimes 1400-1200 – I would suggest setting your idle stop to >/= =3D 1500 rpm and always using fine pitch when on the ground – ideally= , you want a combination of engine rpm and prop pitch such that the airplane won’t roll on pavement when idling without you hol= ding the brakes.

My engine will have a random but freque= nt miss below 1600 rpm. I have the e shaft oil jet mod and would see <27= psi at idle and 65 psi at high rpm. I replaced the stock 2004 renesis regulator with a racing beat 98 psi regulator. I now see about 32 = psi at idle and 85-90 psi at full power.  

 

What rpm do you idle?
