Small Engines (Lawn Mowers, etc.)/lawnmower won't keep running


I have a troy-bilt tuff cut 230.  I have to prime it several times before I attempt to start it. But it shuts off immediately after it fires up. (like 1 second) Is this a carb. problem or a fuel pump problem (do these have a fuel pump?)

Classic dirty carburetor problem.  No fuel pump, gravity fed fuel system.

You can try removing the float bowl nut located on the bottom of the carb to drain the carb gas.  Make sure the float bowl nut holes are clean.

There are 2 springs on you carb.  1 is connected to the governor arm, the larger spring.  The 2nd spring is the choke spring, a smaller spring...DO NOT loose the smaller spring as they tend to disappear when taking the carb off.

Try the float bowl nut tip before removing the carburetor.

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.
