Craftsman lawn tractor model # 917.28826 will not start. I drained the gas last fall, installed new plugs, fuel filter, pre-cleaner, and air filter. It turns over very well but will not fire. I do not remember a fuel cut-off and do not seem able to find one... the old tractor had one. Thanks for your help.

When you say no fire do you mean no spark ,or will not start.

You might check yhe bottom of the carb. For an electric fuel shut off.

How can I find the electric fuel shutoff?

Back to basics:

Check for spark. Remove plug and hold with a piece of wood against the block (metalic). Pull cord and look for spark.

Get some spray carb cleaner and put some down the spark plug hole. Try to start. Does it sputter at least once?

A parts breakdown is available here: http://www.searspartsdirect.com/partsdirect/getModel!retrieveModelDetails.pd?modelNumber=91728 8260&productCategoryId=1509200&brandId=0247&brandDeion=CRAFTSMAN&modelName=TRACTOR&searchedModel=917.28826

Look for a kill circuit problem. But first check for spark.

Its on the bottom of the carb.

Hey people. Got a craftsman 917.28826 24 horse b&s intek motor. Just stopped running last night. Pulling the plugs, wet with gas. Checked for spark, had good spark. Plenty of fuel exiting the fuel line into the inlet for the carb. If I dump a little gas in the carg it runs great till that's gone. Took a screwdriver and tapped the electrical device attached to the carbs float bowl cover, tried to start and it ran for a couple of seconds. Took carb off and inspected the float. Everything was spotless free of dirt and moving as it should. Any visible orifaces ( little holes) looked good. Could it be that electrical thing attached to the carb. Can that be jumped out to see if it's the problem. Any help for this novice would be greatly appreciated.

A little follow up. Tried jumping what I believe to be the electric fuel shut off and blew the inline 20 amp fuse. So I guess you can't jump that out, at least how I did it. I just can't believe from reading a ton of posts regarding similar issues where people go and replace the carb. How the heck does a carb work perfectly one second and the next it's bad. Don't believe it and half the time after being replaced it doesn't solve the problem. Don't really want to be aparts changer rather troubleshoot it appropriately.
