Hi Norm,

I could have but I just write answers so anyone that reads the thread can understand the why part.

As we know.


The ultrasonic cleaner should be able to clean your mower carb well enough on its own but If ultrasonic cleaning doesn’t get all the way into the corroded areas, a combo of mechanical cleaning and chemical treatments may work.

It can sometimes be a bit of a judgment call whether to keep cleaning it or swap out the part

Cheers
Max.
