I found the message I pasted below on this group a few days ago. I had
this exact same problem with the same motor (10A902) 4HP. after
reading all the replies I went and replaced the diaphragm. The mower
now has a steady idle but it is much much higher than it was before.
The mower also seems to run twice as loud as it used to. What do I do

Adjust idle screw.
