In my RV-8A project I find that the spring in the prop governor is so powerful that it puts the prop into the full high RPM setting unless I set excessive throttle friction (one setting affects all three levers on the quadrant). At any reasonable setting of the throttle friction, the prop control won't stay put; it moves forward.
The governor is a Hartzel S-1-0 bought from Van's and the throttle quadrant is the "deluxe" model (there's nothing deluxe about it) from the accessory catalog.
I'm not interested in converting to a separate control for the prop governor. And I think I understand the reason for the spring (high RPM in case of cable breakage).
So what does that leave me for an acceptable method of dealing with this? Is it permissible to "unwind" the torsion spring mounted around the cable-connect arm of the governor to effect less force on the cable?
Thanks,
Joe
