K series oil seals and ignition timing questions
One of my Cubs blew an oil seal yesterday, I can't tell you which one or specifically what engine because I haven't made a thread about it yet and I can't spoil anything. So I will explain this as best as I can.
I replaced this seal back in the winter, so it's new. It's the crankshaft oil seal on the PTO side of the Kohler K series engine, and yes it's from a narrow frame unit. When I installed the seal, I remember it seeming a bit of a loose fit, unlike the seal on the flywheel side, which went in really tight. I guess it was loose, and it wiggled its way further inward until it fell past the wall of the engine block, and into a little space behind the crank bearing. This caused oil to sling out onto the muffler and burn, causing quite the smoke show  So my question here is, how should I go about properly securing the seal so that it won't move again? The seal is unharmed and I can reuse it if I can remove it successfully. Perhaps like some loctite around the outer edge? I'm at a loss here with this. My timing question is more simple. I timed this engine after the seal blew, and I timed it so that the points just open when the flywheel timing mark is lined up. Just making sure here, at the timing mark the points should just be opening up, correct? Simply double checking to make sure I set it right.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.
MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
