Question and Answers

Q:

craftsman lawn tractor model # MS/2666c MS/2666c

A:

Thank you for being Sears’ valued member and for contacting SearsPartsDirect.com with your question about your Craftsman tractor. I am so sorry you are having difficulty locating the parts information for it. I will be happy to help you with this. 
The number you provided (MS/2666C) is part of the Onan engine model number. I reviewed Onan’s model number format and it looks like you are missing a couple of letters at the beginning. For example BF-MS2666C comes up as an Onan engine. You can verify the complete model number on the engine itself. Once you have the complete engine model number, we will be able to assist you with parts for the engine. 
 
The tractor has a separate model number. It is usually located on the fender below the seat. We will need that model number to find the tractor parts such as blades, belts, pulleys. Our Craftsman model number format is 3 numbers, a period and 6 more numbers. I hope this answers your question. Thank you for choosing Sears, we appreciate your business.

Q:

No Spark BF-MS2666C Onan Onan engine

A:

Hello glad to help.  Thank You for choosing Sears PartsDirect.com

I am sorry and do understand your frustration when there is problems with the Onan engine.

Glad to help out.   Im  looking at your Onan model number  bf-ms266c.

 Onan engine, don't see too many of them.  They are usually great engines when people take care of them.  

When it comes to getting a spark to the engine the two main key ingredients are the coil and the spark plugs.  I would change the coil and get the 2 spark plugs also.   You need to make sure the spark plugs are properly gapped and when you get them from us at Sears, they are.

Coil for model bf-ms2666c

spark plugs for model  bf-ms2666c

 If you have further questions please let me know.

Thanks for choosing Sears PartsDirect.com

A:

I don't know that the external pump would cause this problem. Most likely the problem is with the needle and/or float in the carburetor. The float is brass and over time they can develop small holes which will allow fuel to get in the float and then it will not close anymore. If you determine this to be the problem you can replace the float with part number 146-0380. If the float looks good then it could be the needle/seat causing the problem. You can clean all that up with carb cleaner and replace the needle and seat assembly with part number 142-0553.

You can order those parts HERE if needed. Also you can go there and use the engine model number to pull up the parts images for any other parts you may need.

Thank you for using Manage My Life!
