prop sync
Pete,
The prop sync light comes on, it blinks, never burns steady. The set up I have has a two position switch (off-on) and a knob. Neither seems to do anything, except turn on the blinking light! The sync meter on the panel works, and when you sync the props by hand, the meter indicates this as the needle stops moving back and forth. I have JPI digital tachs, so getting the props in sync is easy. The problem is the rear prop never stays at the same RPM, it varies +/- 50 rpm or so, this drives one crazy after a while! if I could get it to stay, I wouldn't care so much, but it refuses to do so. Too much slop in the rear prop cable I suppose. I will see if anyone knows where to get a hold of the test box. The shop is looking at the pot on the rear governor. My set up is like the one in the Service Manual for P3370292 and beyond, it was modified with a service kit that came out in the late 70's. Any other suggestions would be most gratefully received!!
