Need some input from the Vans brain trust. Was going to fly the plane for the first time yesterday and the prop would not cycle. I had to get a customer lenth prop cable and with trying to limit the ground run time till yesterday had not run the engine since I got the cable installed.
Anyway, we had several really smart people around with lots of RV time. After getting it warmed up and still not cycling we pulled the prop to make sure there was no crank plug (IO-390)- and there was not.
Setup (all new)
IO-390
Hartzell Composite CS Prop
Hartzell prop governor (from Vans)
Steps we took:
Verified the stops were both being hit
Removed prop looked for crank plug- no plug, but we did not get very much oil that drained out either.
Warmed up again, took to 2200-2300 RPM, would not pull down other than one very small pull once but would never do it again- had Mike Seager sitting next to me running the controls so no user error )
Pulled the governor to make sure the prop circuit was not being blocked by a gasket, etc. - all good
Re-clocked the gov to the RV-14 instructions. I think this is more mounting/angle but we tried.
Reinstalled and tried cycling again and nothing
Thoughts? or ideas? Anyone ever see a bad governor out of the box? Hoping not an internal engine issue. Sticky prop?
I found this article and seperate Lycoming SB that I'll attempt. May need to make a block off plate for the lyc DB.
Seem like the avweb one is easy and should be where we start.
