Experience
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. I received a scholarship from the Air Force and am currently pursuing another degree.

Question
I have a 15 hp Kohler motor Craftsman Riding Lawn Mower. The problem I'm encountering is, when the mower isn't running gas gets into the oil. Could the electronic part on the bottom of the carb be the problem? I would appreciate any information you may have on this subject.
Thank you for your insight.
Answer
The most likely problem is the inlet needle. Depending on your engine model number, you may have a brass float and a replacable inlet needle seat as well.
If the inlet needle has what looks like a rubber tip then the seat is probably not replacable...just replace the inlet needle. If you have as all metal inlet needle you will have to replace the inlet needle as well. I would also check the float to make sure it does not have a pin hole in it.
An alternate solution is to just install a fuel shut-off valve in the fuel line. Cheap, easy to install and works everytime as long as you remember to shut-off the fuel when you are done mowing.
Let me know if this helps.
Eric
