It's funny that you mention the slobber clean up.. On my Venture, when I broke in the Saito 91, I ran a short chunk of old garden hose into a quart oil container to collect almost all of the stuff. Just cut a 3" notch in the end of the hose that goes in the oil container so there is no backpressure. I had nearly a half quart when I was done. The reason I do it on the plane is because I do it outdoors anyway, and I get to find out if the tank is in the right position along with the final plumbing.
