Your Craftsman is powered by V-twin Kohler with OHV and a pressurized, fully filtered lubrication system. You cannot compare one of those engines to the L-head Kohler K and M Series engines on the issue of oil consumption. The modern OHV twins have much tighter tolerances in their design and manufacture.
Therefore, I do not dispute what you report about that engine. But this is an apple to oranges situation and unfortunately, so many of these discussions end up that way. One person cites their personal experience with their OPE but they do not take into consideration the technology differences.
Fords, Chevs and Dodges built in the 50's and 60's came with engines that routinely burnt about 1 quart of oil every 1000 miles or so. As someone who worked in Service Stations back then, it was routine for me to pop the hood and check the oil on every car that pulled up to the pumps for gas.. Those days are gone. Better metallurgy, better design, tighter tolerances etc all provide engines today that don't consume a pint of oil in 5000 miles or more
I cannot comment on your Briggs engine because I am not familiar with them.
