Thank you for your question.

I am sorry you are having a problem with the trimmer. If you are having a problem with the engine running, I recommend checking the fuel first. If the fuel is older than five weeks, pour it out and refill with fresh fuel. Most of the carburetors used today cannot be adjusted or require special tools to make the adjustments. If the trimmer is not running correctly you can try to clean the passages in the carburetor. To do this you need to remove and disassemble the carburetor. Then spray all the passages with carburetor cleaner. Once clean, reassemble the trimmer and check the operation. If it still runs rough, I recommend replacing the carburetor. The reason is the cost of the carburetor is $16.00 from out parts website:

Sears Parts Direct

. The part number is 753-06288.

Please let me know if you need further assistance on the repair of the trimmer.

If you do not feel confident repairing this problem yourself, then you can have it repaired by a Sears technician. Here is a link that will provide the nearest drop-off locations:

I just received a new Craftsman model 316.791190 trimmer as a gift. Right out of the box it will not fully accelerate. I have had a lot of trimmers and two cycle engines in the last 50 years. It is obvious to me that the high speed screw on the carburetor needs adjusting. I have been able to adjust carburetors to solve such problems many times using a screwdriver. Now you have a carburetor such as what is on this trimmer that you need special tools or needle nose pliers to try to adjust. So if you are not experienced enough to know such things you will have to take it in, right out of the box, to get it serviced. If this is Sears approach to drum up more business they are mistaken. I am in touch with a lot of people on the internet and will tell them to think twice before they buy such equipment from Sears again.
