Many owners are tackling their own mower maintenance and carb adjustment. I found that your model has a carb tune up kit at Sears Parts Direct so I attached in the second link below. I also found a previous expert post that has an attachment for carb adjustment that may help. Finally the owner's manual is often a good place for service and maintenance information. That is the third link. Hope this information helps.

Thank you for your question.

I am sorry you are having a problem with the mower. I have looked up the model number you have submitted. The carburetor on this mower is not adjustable. If you are having a problem with the carburetor, I recommend checking the fuel first. If the fuel is older then six weeks old it should be replaced with fresh fuel. If you still have problems, I recommend cleaning the main jet in the carburetor. I have found a video showing how to clean the carburetor. Please click here to watch the video. We usually find the small holes of the main jet are plugged.

I hope this is helpful.

Please reply below with more details if you need further assistance.
