Default Proper break in of rebuilt Cub 149 motor

Gentlemen!

I've just had a Cub 149 motor rebuilt. I had the piston, rod, rings, governor gear, and gaskets replaced with all genuine Kohler parts. What are some tips for breaking in the motor properly and what things should I avoid like the plagued? Also, I've heard from one source not to run the motor wide open for awhile and from someone else that it is supposed to be run wide open. Because I've been without it for a year, I was anxious to cut with it, and I did cut some pretty thick grass for about an hour and a half at about 60 percent throttle. Also how soon should I change the oil? And does anyone recommend synthetic Lucas oil additive to prevent dry starts? Also I was told that there were some sort of 'bushings' or something in the motor that helps with vibrations...that should've taken out at the the time of the rebuild and I'm not sure that they were. Will these "grenades" go off unexpectedly in the future? I wish I had consulted with you experts before I ran the 149 at all, and hopefully no harm done... but I'm sure your advice can greatly benefit me from this day forward. Thanks for your help and expertise, and any other related tips are greatly appreciated.

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.
