Question and Answers

Q:

Starting model #31C707 Type#0603-B1

A:

Thank you for your question. I am sorry you are having a problem with the engine. I will be happy to assist you diagnosing the solenoid. The image below show how to check the solenoid. If the solenoid is working I recommend pouring in a thimble full of fuel into the throat of the carburetor. Then try to start the engine. If the engine starts and dies I recommend cleaning the carburetor. I found a website that shows how to clean the carburetor. Click here to be taken to that site.   I hope this is helpful. Please let me know if you need further assistance. Thank you for using Manage my life. Mark

Q:

Engine will not start -- no gas to engine see details: Craftsman Lawn tractor model 917.273372 B & S 17.5 hp engine model #31C707 Type 0230-E1

A:

Thank you for your question.

I am sorry you are having a problem with the tractor. If fuel is not getting into the carburetor I suspect the problem is in the needle and seat. To access the needle and seat you have to remove the float bowl. Then pull the hinge pin that secures the float. Be careful the needle is attached to the float. Once the needle is removed, the fuel should start coming out. If it does not come out, you need to remove the fuel line from the carburetor. If you have fuel coming out there, the inlet is plugged. To clear it out you will need some carburetor cleaner. Use the straw to spray into the hole where the needle goes. The carburetor cleaner should come out where the hose connects. Once it is cleaned out, I recommend replacing the line between the carburetor and the fuel filter. Overtime the hose can break down and come apart inside.

I hope this is helpful. Please reply below with more details if you need further assistance.
