gwest_ca-(File Mod) 10,488 #2 Posted May 22, 2016 Here is the Kohler service manual Tried to determine what kit you need but didn't have any luck. The online parts lists don't seem to have it either https://www.partstree.com/parts/kohler-engines/engines-horizontal/m14-601559-kohler-m14-engine-magnum-wheel-horse-14hp-10-5kw-specs-601500-601557/ Garry ADDING The on-line list shows a replacement carb kit 47 853 29-S which is the complete carb. If you hover over the note it shows a carb number 47 053 96. If you go to pages 3.10 and 3.11 in the carb manual they list the parts for that carb including a kit. Perhaps that is the one you need. I don't know if the original carb and the replacement are the same. A Napa catalog shows the carb kit as 25 757 11-S which matches the info in the carb reference manual.
