Hi,
Have read various postings with no success. I have a model #445677 Craftsman 24HP riding mower, about 3 years old. The engine cranks but won't run. For awhile if I took off the hose off the outlet of the fuel pump and leaked some fuel, the engine would catch and run fine without quitting. But leaking some fuel no longer works. I suspected the fuel supply as the hose from the vacuum fuel pump to the rocker cover was cracked, so I replaced the vacuum hose to the rocker cover. The replacement hose was shorter than the original so I added a length of fuel hose to make up the difference. I'm pretty sure the hose is air tight. While the engine cranks, it won't catch and run. Sometimes it comes close and it seems one spark plug might fire once but the engine won't catch. After replacing the vacuum hose, the fuel pump seems to work better, when I take the hose off the outlet (the hose that runs to the carburetor), a stream of fuel gushes out and seemed to be under pressure. Taking out a plug, the plug is mildly damp and I can smell gas but it's not soaked. I'm sitting squarely on the seat and the left pedal is pushed down when I start. But I don't know if I'm missing any other safey lock-outs. I'm not familiar with the electric ?? fuel injector, if that's what it is under the carb, and how to test. I unplugged the connector and applied dielectric grease to the contacts. I may be overlooking some other safety lock-outs. Writing this, I'll do a spark test tomorrow, will take out a plug, ground it and crank. In the meantime, what am I missing here? Pictures posted below for reference. Thanks for any suggestions.
