I did my second engine run today on my RV-10. First start a few days ago for 3 minutes. No issues. Ran today following the Lycoming manual for a fresh install. Basically warm up at 1000 RPM, run at 1500 RPM for 15 minutes while watching CHTs and pressures. Do a mag check and cycle the prop, Run up to full power for less than 10 seconds, pull back to idle, and shut down. Shut down if anything is out of the ordinary.
Thi is a new IO-540-D4A5 and new 2 blade Hartzell - stock right from Van's. All went well in everything except the prop doesn't cycle.
At about the 10 minute mark running at 1500 I tried several times and nothing. Then I ran up to 2200 and tried again. Nothing. Back to 1500. Tried again. Nothing. Back up to 2200 again and still nothing. I aborted the test at this point, not going the full 15 minutes. Backed off to idle, then up to 1000 and shut down.
CHTs got up to 350. Oil and fuel pressure were in the green. Oil temp seemed a bit low for the whole test, only reaching 151* F.
Any suggestions on troubleshooting the prop cycling issue?
