I have owned my Craftsman DYT 4000, 18.5 hp Briggs since 1996. during that time I have repaired or replaced most everything, except the steering wheel.
It sat last summer due to the heat and drought. Inspected it before use and bought new blades, spindles, bolts and belts. Got a new battery, new carb and found a fuel leak in the rear. Fuel line broken where it enters the tank. Replaced fuel line and installed new fuel filter. Put in better fuel cut-off switch, new fuel lines everywhere. New filters. Changed oil and plug.
Started up right away. Ran as good as new for about 1.5 hours, then started backfiring. Complete lack of power, would not even turn the blades. Limped back to the patio (i.e. workshop). Next morning, same thing. Ran great for about 1.5 hours, then no more.
It looks like it is getting enough fuel, but I ordered a new fuel pump.
It is not burning oil or blowing any smoke when it fails. Just a lot of backfiring and jumping around.
Any thoughts would be appreciated.
Thanks!
