Electro12WH 50 #1 Posted October 17, 2008 I have had an ongoing issue with that high speed miss, stumble, cough that is common to K series engines. Yes, I know it is normal, but annoying. Any ideas on how to get rid of it? I have changed to an Autolite plug, no luck. Is this a carb. issue? Electrical? Every Kohler I've had did this. Share this post Link to post Share on other sites
big mike 13 #2 Posted October 17, 2008 In all the Kohlers I have had(30-40) the carb problems are usually solved with a soaking in the carb cleaner can and a new kit. A high speed stumble sounds like a carb issue. Share this post Link to post Share on other sites
