wh1075 6 #1 Posted May 7, 2023 I have a question regarding identifying carburetors on Kohler K series engines. I have downloaded the Kohler Carburetor Reference #TP-2377-E from the manuals section. While this is helpful it does not answer my question. I have 855 and 857 tractors with the K-181 engine. Both have Carter model N carburetors. I am unable to find any information about these. I have an 877 with a K-181 with the OEM Kohler carb. # C-231738. Were the Carter model N carburetors used by Kohler? Are there any guidlines for preliminary settings? Thanks for any assistance.

This is a pic of Trina's Military Tribute Tractor "Millie" which is an 856 originally. That carb is OE on mid 60s Kohler 8 HP engines. Both Carter and Kohler were used. I've been using the same initial set-up for either. 2 Share this post Link to post Share on other sites
ri702bill 8,327 #4 Posted May 8, 2023 There is a size identification number cast into the body. With the choke open, look UP in the bore above the choke plate - should be something like 20 or 22. The larger the number, the bigger the carb. 3 Share this post Link to post Share on other sites
wh1075 6 #5 Posted May 8, 2023 Thanks for the replies. I will try using the preliminary settings for the Kohler carbs on the Carter model N's. Also thanks for the tip to look for the ID number in the casting. 2 Share this post Link to post Share on other sites

Are you having issues with them holding adjustment? 1 Share this post Link to post Share on other sites
wh1075 6 #7 Posted May 8, 2023 One carb is on an engine that I have only recently acquired. I am having difficulty getting consistent performance across the throttle range. If it runs decent at idle then it runs poorly at higher rpms. And vice versa. My initial inquiry was to determine preliminary settings as a starting point. I have not rebuilt the carb since I have owned it. 1 Share this post Link to post Share on other sites
