I have a 134 NAA engine that does not respond to the throttle
position correctly. It also speeds up whenever it wants to, slows
down with any load, does not compensate for load changes, etc.
Early flyball type governor.
So I ordered some new gaskets, shaft seal and flyballs hoping to
rebuild it. When I got it apart, the flyballs do not have flat spots.
They look pretty much like the new ones. It was a little gummed
up with older oil, so I've been cleaning it up and inspecting.
I've got the governors off two engines here in front of me.
The thrust bearing in one is shot. The other looks Ok.
Both have a ridge where the thrust bearing rides, one worse
than the other. (the one with the bad bearing)
The cupped portion does have six little flat spots on it that the
one with the bad thrust bearing does not. Pictured.
Could these be enough to cause my symptoms?
There are no groves in the case like I've seen on the N series.
What else should I be looking for that could cause it not to work?
