GLEN - If you just did a new O/S piston & rings, valve grind, etc it will take a while for the new rings to seat. OEM Kohler rings are chrome plated and they can take 100 operating hours to seat completely.
I would think the smoking & oil consumption would be about Zero within 10-12 hrs though.
Main thing when breaking in an engine is to MAKE IT WORK. Mow grass, plow at a PD, get it nice and warm for 5-10 minutes then let it cool for a couple minutes, then get it hot again. Vary the RPM, but do not let it idle at slow speed for anymore than a minute or so. Follow the break-in service in the Kohler manual, 30 weight non-detergent oil for the first ten hours, then use your favorite oil. Staight 30 weight low ash Case IH oil is good as are many others.
