Thank you for your question.
You are mostly likely correct on the diagnosis on the mower. Cleaning the carburetor should cure the problem you are having. Explaining how to clean the carburetor can be difficult. I have found a few videos showing how to clean the carburetor. Please click on the following link to view the videos. Both show taking the carb off the engine but I usually just tip the mover with the carb up. Then remove the float bowl and clean the jets with the carb cleaner and a bread tie wire. Once the jets are clean, I reassemble the carb and test. If the mower does the same, I recommend replacing the carb instead of ordering a rebuild kit. There is usually much difference in price.
I hope this is helpful. If you need further assistance, please reply below.
