Small Engines (Lawn Mowers, etc.)/B & S Carb # 498298


My Craftsman front tine tiller (917.292403) will only keep running when the manual choke is partially engaged.  I suspect the carb needs to be cleaned and rebuilt. Is there a rebuild video for this carb available somewhere?  I have searched YouTube with no success. Perhaps there is a B & S manual something like Tecumseh has available?  Can't find that either.  Can you help? I need to get this going before the spring planting season.


Sears for "briggs and Stratton 5hp carburetor cleaning" on You Tube.  Lots of videos as this is one of Briggs' most popular engines.  The control rods/linkages can be a little challenging.  I find it easier to just remove the engine shroud, the part with the starer rope, as this will give you a lot more room to access the linkages.

I would go ahead and buy a diaphragm and a couple, that's right, 2 carb to tank mounting will most likely need them.  Some of the 5 hp Briggs use 2 gaskets for the carb/tank mounting.  Pay attention to see if you engine uses 2 gaskets or one thick gasket.

Do you have an air compressor to blow through the carb orifices?

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.
