I have a lawnmower that runs for a short time and then dies. If I pump the primer it will start again and then die a short time later.

The mower model # is 917.371603, it is a Briggs&Stratton 6.25 hp engine. Please give me as much instruction of how to clean the carburetor as possible and any other info available. Thank you.

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.
