Small Engines (Lawn Mowers, etc.)/Kohler Engine


Hi Eric, I am trying to find parts for a Troy Bilt tiller with a Kohler engine. The engine spec number is 281271J. The motor serial number is 10245775. The model number is K161t. I think this is a 1981 year model but not sure. It has a 7hp engine. The owner says it will idle and he has to throttle up very slowly to get the engine to rev up. The carburetor has an idle adjustment screw, an adjustment screw on top of the carburetor and one other adjustment screw. I am thinking of putting in a carburetor kit if I can find the correct one. If you can find a link to this carburetor kit, I will appreciate it.  Also, do you think this carburetor could be adjusted where it will run right as is?  If so, will you please give me instructions on the correct procedure?  I have put a needle and seat in 6hp Briggs and Stratton with good success, but I've never worked on a Kohler engine before.  The owner said that he had the engine rebuilt sometime in the past. Thank you in advance for volunteering your time and expertise.  Stephen

Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. Continued working on mowers part time as I completed 20 years of military. Retired from the military on a Friday and continued in the lawn and garden industry the next Monday.
