CatsClaw 0 #1 Posted 15 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 31,705 #3 Posted 15 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. 2 Share this post Link to post Share on other sites

WHX?? 56,424 #6 Posted 4 hours ago Many times you will see a Chumponion LM14 i think it is which is a J8 sub. 3 hours ago, squonk said: I have an Autolite 295 in my K90 Keep in mind this is AI ... The most direct and commonly used equivalents for the Champion J8C spark plug are the NGK B6S, Autolite 294, and Denso W16S-U. These are standard, 14mm thread, short-reach plugs designed for small, 4-cycle engines, with an approximate heat range equivalent to a 6 or 7 in NGK terms Share this post Link to post Share on other sites

I believe the 294 is a colder plug Share this post Link to post Share on other sites
CatsClaw 0 #8 Posted 3 hours ago Thanks for the info. Where do you guys buy the autolite 294's? Can't seem to find them. Share this post Link to post Share on other sites
CatsClaw 0 #9 Posted 2 hours ago I did find Champion J8C Part Number: 841 with a pre gap of 0.030. Would these work or should I go with the Autolite 294? Anyone know the best spark plug gap for the K90/K91's? Share this post Link to post Share on other sites
squonk 46,340 #10 Posted 2 hours ago I'd use the Autolite 295 Share this post Link to post Share on other sites
