Hello Joe. Thank you for choosing Just Answer. My name is ***** ***** I will do my very best to get you the answer you need to your question.
Can you describe the erratic behavior of your mower to me? Can you describe the maintenance you performed on your carburetor?
Customer: replied 1 year ago.
The erratic behaviour is like you can see it is running and lowering the engine consecutively... I took the carburetor out (assy bb62z b - Honda Motor 752H652561 160cc) following some instructions and did a clean out completely... besides all the troubleshooting I made and still the engine has the same behaviour erratically....

Did you totally dis-assemble your carburetor, and soak it prior cleaning it?
You very likely, still have a clogged jet or fuel passage, although you have already cleaned your carburetor. The jets and fuel passages in carburetors, are getting smaller and smaller, due to new epa standards. This makes cleaning a effectively, carburetor more difficult.
