Gang,
Our experience has been that the sump scavenge pump is unnecessary on these small radials. On the big ones there are obvious benefits, but if you have the oil shut off and an intake drain, you virtually eliminate hydraulic lock (still need to pull through tho'!), and eliminate the mess on the hangar floor. The pump seems to me to be adding unnecessary complexity and cost. Though some argue that about the shut off valve, and that's the long running great debate.
As for when to pull your engine through....guys....read the book. Speculation, and inaccurate at that, on this list doesn't help anyone....
Spring time is a great time for systems reviews....while you're looking up the spec. on proper preflight of your engine, there are a few other good refreshers in there as well.
<stepping off my soap box now>
Happy Flying,
Barry
