I decided to leave the static alone and just do the inflight test. Made the adjustment required and overshot by 30 rpms or so. Readjusted and ready to go. Very simple and straight forward. I tried a much slower application of power during takeoff and no longer have the "overspeed" situation. Thanks all.

I had to replace my alt belt and was shocked by the amount of sludge caked inside the crank. This the stuff that will corrode the crank from within. I cycle my prop almost at every flight. I had to build a scraper from a piece of alumn strap to scrape the sludge. No amount of thinner would clean it. The stuff was grey (i assume metal) and most of it was the consistency of proseal. Some was dry and came off powdery like. I am thinking that two years and couple hundred hours might be the good time to clean the crank. It would be nice to know other people experiences.

It is similar to proseal as you say. My guess is that there may be metal there but a lot of it could be blow-by lead from the fuel that collects in the oil too. I'd say it cakes on to about 1/4" thick or so. Tim On Oct 15, 2011, at 7:02 PM, Rob Kermanj wrote: > > It has been 360 hrs and four years since my prop was off the plane.
