Q:

Good crank but no fire 917276411 Craftsman Tractor

A:

Thanks for the inquiry and for being a valued member.

I am sorry to hear of the starting issue you’re having with the tractor. I know how frustrating that is to have happen.

There are three basics the engine needs: Ignition, Compression, and Fuel.

First, go back to the spark plug. Remove the leads, or wires, that connect from the engine to the plug. Remove the plug and put them back in the leads. Now position the leads so the metal end of the plug is against the engine or another clean unpainted metal ground point. Keep your hands away from the plugs so you do not get shocked, and turn the key to the start position. Look for sparks at the ends of the Spark Plug. Look carefully as they might be hard to see in sunlight or other bright lights. If there is spark there then you have ignition, the first of the three basics. If not, you likely have an electrical problem that needs to be traced.

The engine should have been spinning over faster once the plug was removed and you should hear air rushing out of the spark plug holes in puffs. You could even try putting a thumb or finger over each plughole to see if the pressure pushes your finger off when turning over, just be careful not to touch the grounded plugs so you do not get shocked. If that all happens then you have the second ingredient, compression. If not then you may need a valve adjustment or may have a broken component inside the engine.

That leaves fuel. Check the tips of the plug you just removed, if fuel is reaching the engine there should be some residue there and they should look somewhat wet. If you used your finger to check compression then you may even see some residue on your finger. If there is fuel here, your problem may be old fuel or a timing issue. Try putting a small amount of good fuel into the throat of the carburetor and turn the key to start. If your problem is fuel related only, the engine should now try to start, or even run, until the fuel you put in is gone. That would indicate the fuel supply is being stopped in the fuel tank, fuel line, fuel filter, fuel pump, or carburetor. Some carburetors have a solenoid to stop the fuel supply when the key is off and a malfunction there could also be the problem. 

If you would feel more confident have a Sears Home Service technician help assist with the diagnosis/repair, you can call 1-800-469-4663, or click here to be directed to the page to set up service.

Q:

t tractor starts runs for a bit stalls out after a short time .inged the fuel filter and plug .what else could it be ?trtor model 917.276411 7.76411

A:

Thanks for the inquiry and for being a valued member.

I am sorry to hear of the issue you're having with the tractor. I know how frustrating that is.

The most likely suspect would be with fuel. Due to the fact that it starts and then shuts off after a few would be indicative of a dirty or partially clogged carburetor.

I would pull the carb from the engine. With a full can of carb cleaner, a wire brush, and a bread tie wire to poke through and clean the main jet; I would recommend a very thorough cleaning. Start by taking off the float bowl. Douse it very liberally with carb cleaner, and undo the pin for the float, and remove the needle and float. Clean them very thoroughly with the wire brush and carb cleaner. Pay close attention to the seat the needle sits in and clean it well. Once clean, start brushing the carb bowl and body and make sure you get all the varnish out. It may take three or four brushings with carb cleaner dousing in-between. From there, take the straw of the carb cleaner and shoot carb cleaner through any little hole or passageway of the carb. Shoot out the throat of the carb and poke the main jet with the bread tie wire. You have to make sure you get everything the first time, if you leave anything behind, it’s likely to reclog once you have it reassembled.

A:

Thank you for your question.

I will be happy to assist you with this. Part number 155046 is the idler arm. This part should pivot back and forth to tighten the mower deck drive belt. If the idler does not move when you engage the engagement lever, I suspect the pivot is rusted. To cure this, loosen the pivot bolt and soak the pivot with WD-40. Then work it back and forth until it is free. When it is free tighten the pivot bolt and check it by hand. If it is still free, it should work fine.


I hope this is helpful. If you need further assistance, please reply below with more details.
