I recently inherited a Craftsman lawnmower with a 190 cc, 6.5 HP 120000 series B&S vertical shaft engine completely apart. I have reassembled most of the internals, but I have some questions concerning re-installation of the internal governor assembly, which drives off the cam gear. My questions are: (1) does the conical gear on the governor assembly need to be aligned with any specific mark on the camshaft gear; and (2) does the governor assembly need to slot into a specific position on the crankcase cover. Any advice for reinstalling this governor assembly will be appreciated. Thanks.

I have a Lazer Z with a Kohler Command 25 motor. It leaks a huge amount of oil, but I cannot figure out the source. Placing a piece of cardboard under it has not been helpful in finding the leak. The oil pools up on top of the motor, between the cylinder heads. If you stand at the back of the mower facing it, the oil is pooling closet to you ( i think it is opposite the carburetor). Could it be coming from behind the heat shields in front of the cylinder heads? Not knowing much about these motors, it "seems" like it could be valve cover leakage, but it sure is leaking a lot. Any advice or links to kohler diagrams would be helpful.
