posifour11 723 #1 Posted March 19, 2014 I am having a heck of a time finding parts for the new k90 I just lucked into. On the usual parts websites, its not listed. The k91 is and even the spec number for my engine. Help! Share this post Link to post Share on other sites
Lane Ranger 10,943 #2 Posted March 19, 2014 I know this too! I have a K-90 block with K-91 bearing plate, magneto and flywheel parts that will work on the motor. Not sure about other -crossover parts. Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,029 #3 Posted March 19, 2014 Have never had a 9x engine but wonder if it wasn't simply a name change to meet the demands of the future at the time. The 1st number or numbers are the approximate cubic inch displacement and the 1 or 2 following are the number of cylinders. Took me a long time to realize that.

TT-(Moderator) 1,131 #4 Posted March 19, 2014 The list for the K-90 & K-91 engines are combined on many parts look-up sites. If you found the spec number of your K-90 engine and it's listed as being a K-91, that's probably why. It's not the first time incorrect information has been found on a website and it won't be the last. I have more faith in the OEM manuals, but they aren't guaranteed to be correct 100% of the time either. There are differences in parts, but a lot of them are upgrades to the ignition, connecting rod style, starting system,etc. The basic design was unchanged throughout the 20 year+ production run. If you can't find what you're looking for online, post your request(s) here. I have a couple of old Kohler dealer manuals and would be glad to help. Share this post Link to post Share on other sites

Desko 608 #8 Posted March 26, 2014 I love how the badge tells you point gap plug gap and oil capacity. I can't tell how old it is but it looks old 1 Share this post Link to post Share on other sites
