Small Engines (Lawn Mowers, etc.)/22hp Briggs Stratton mounted on Craftsman


Riding mower will turn over but not start. Have rebuilt carb, checked solenoid, replaced. fuel pump and filter, spark plugs..  When I replaced pump I pulled hose from front of carb o see if fuel would cycle through pump and it does not reach carb. wondering since pump is vacuum can it be a compression problem? have checked hoses all are good.  also fly wheel seems to be very easy to turn by hand, much easier than my other mower?

22HP B&S 40h777-2041-E1

If fuel is not being pumped via the fuel pump the engine will never start.

I would remove the spark plugs, dis-connect the fuel line from the carburetor, crank the engine and see if the fuel pump squirts fuel.

Let me know if the fuel pump squirts fuel.

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.
