Prop Governor and Synchro Slave

[hharney]

The aircraft is a 77 G Model, normal aspirated. The rear prop governor was just repaired by a reputable prop repair station. The repairs were made to the synchro gears and potentiometer. The governor was returned as "good to go". It was overhauled just 200 hours ago in the year 2000 when the prop was OVH. The aircraft Service Manual indicates that this model or type was used on #1816 and on. The aircraft is earlier than #1816 so there is a question as to why this type governor is on this aircraft as it appears to be original equipment. Looking at the figure from the SM the high RPM stop is different than the photo of the unit on the aircraft. The photo from the aircraft appears to have a bent stop screw and is not contacting the stop plate square. The shop says it is ok and that all these governors are like this. It just doesn't look right. Does anyone have a similar governor setup with this Syncro system? Could you please verify the photo and comment.

For those that have prop synch, is it worth the hassle to keep?
