Sears Craftsman rider Model # 917.270770 won't stay running
I have a Sears Craftsman rider that has been very reliable for many years. I had it serviced this Spring, then I had trouble with it flooding (that's what my service guy said). He came back and put a shut off valve in the gas line. i still had trouble keeping it running. He came out again - blew really hard in the gas tank - it started and it seemed to be ok for a very short test drive. So that's what I've been doing - blowing in the gas tank really hard (yuck). I was not able to keep it running the other day and had to give up. I love my mower! I think if i knew what to do - my service guy could fix it for me. Help! thanks so much

When it dies does it shut off like you turned the key off or does it spit and sputter like it is running out of gas, does it puff black smoke before it dies? Have a good one. Geo

It doesn't shut off, it just dies and I push the choke back in and turn off the key. When I try to re-start it, the engine turns over but doesn't try to start. After that if I blow in the gas tank k & try to start it, a puff of blue smoke comes out. I'm afraid I'll run the battery down if I try too many times.

The gas cap needs to vent; I would start by cleaning or replacing it. Might do a test first, parked in the driveway or wherever, not a full tank so it doesn't slosh all over the engine, and see if it stays running with the cap off.

The carburetor needs repair to stop the gas leak. The fuel shutoff is a bandaid to cover the problem, not fix it. The needle valve is leaking.
I suspect that your fuel filter is clogged or the fuel lines are collapsed, impeding the flow of fuel to the carb. This would be why pressurizing the tank is getting it going again.

I took the gas cap off and it went around the yard once - then it died again. I read someplace about another sears craftsman mower with a similar problem - they were told there is a nut holding the carb bowl on, which is the main jet. And there is a small hole that gets clogged up & to clean it out with a small wire. Does that sound like something I should do?
I haven't been using the fuel shut off after it was put on, as flooding doesn't seem to be the problem.. I'll ck the fuel filter and can you tell me where the needle valve is please? Thank goodness for the internet - thanks so much for your help!
