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 3 year old craftsman lawn mower.
Can you explain in detail about how to Clean the Carburetor.
I change Air filter every year. There is a small plastic tube in the hole where Air filter is plugged. What is the function of that tube?
Answer The tube is an air vent to allow the fuel bowl to match atmospheric pressure.
To clean the carb you will need to dis-assemble it; mainly just removing the float bowl nut, bowl, float and inlet needle. Normally all we do it blow compressed air from and air compressor through all the orfices in the carb. There is the main fuel tube that runs up through center of the carb, the float bowl nut orfices and the orfices in the ventri side, the air filter side, of the carb.
If the carb has severe build-up we will remove the primer bulb, butterfly shaft and soak it in some strong carb cleaner.
