Situation: new build RV-8 with Superior IO-360M1S, Hartzell G2YRN/7605W-2X, PCU5000 governor.
No issues on the ground. Runup is good and prop cycles as it should. Engine will idle down to 600rpm.
In the air when I pull the throttle to idle I’m still at 1600 rpm. I can pull the prop control back and the rpm drops to flight idle. If I push it forward the rpm returns to 1600.
Just wondering if anyone has had this happen and if anyone has suggestions of what I should do/check?
I’ve talked to the guys at Aerosport Power, PCU guys and one Hartzell rep. No solutions as of yet.
Thanks in advanced.
