CatsClaw 0 #1 Posted 10 hours ago A friend has an old wheel horse that is supposedly a 1960 model with a 4 hp kohler. K90? The tags are missing so assuming it's 1960, what spark plug should he run in that kohler? Share this post Link to post Share on other sites

Achto 31,701 #3 Posted 9 hours ago If it has the correct engine for '60 it would be a K91. Only real difference between a K90 and a K91 is the governor setting. 3600 RPMs for a K90 - 4000Rpms for a K91. Share this post Link to post Share on other sites
