Hello and Thank You, New to the Forum with a Craftsman T-2500 (917.255. . .) 46 inch deck 3 years old. A month ago I am happily riding and mowing on level ground just making a summer pass over the weeds when for no apparent reason the engine just stops, no clink, clank, cough, just stops. Gas tank half full. So, off I got, scratching my head quite perplexed. So, old school thinking . . . fuel flow or no spark . . . pulled the spark plug, ground it turned the engine saw decent spark, so must be fuel flow, wondered just where the electric fuel pump must be. Quite surprised to discover it had a vacuum driven fuel pump, my first experience with such a thing, but finally figured that out, so pulled the fuel line at the carburetor and had a gusher of fuel flow. So, good spark, good fuel, why no go??? The odd thing, I can get the engine to crank by standing next to the mower stepping down on the "parking brake" and turning the key and not sitting in the seat. I have downloaded the manual and some of the schematic details and I am hazarding a guess that somehow the safety switches have failed or crossed over or ???? So I am turning to the experts who in all their multilayered experience and wisdom have most likely encountered this same baffling problem and found that it was just the thingamgig that had gotten disconnected form the watchamaallit and all I need to do is reboot the main drive and download the quick fix patch for Windows 3.1. Now I am off to a meeting for the next few hours, but all along while the others are musing over the topic I will inwardly anticipating the simple fix and perhaps even later this afternoon happily encouraging the weeds to stand tall and receive a trim.
