That shift mechanism sure looks like the one on my wife's machine...
There is a company in the USA called " Dinosaur boards " I used to purchase aftermarket regulators and control boards for Onan Generators Obsolete parts.
Prices were rock bottom.
The core charges were very low
I clued into shortly that I was never getting a refurbished board they were always new.
My other supplier Flight systems could never repair a board for that price always two or three times as much.
One day I went on a search after discovering the parts were coming from China.
A referb Flight board was 400 bucks
A Dinosaur was 125 bucks
The Guy in China making them charged me 59 bucks.
Now I search for Chinese parts because most of the time they are made there anyways.
Its just a question of finding the the supplier or a supplier that wants to muscle in and clone a part.
Making boards and assembly in a mom and pop shop is very cheap.
I found a lot of this in Asia.
An Indian company that will cast and machine parts.
A Chinese company for electronics
A Company in Vietnam that will make gaskets and rubber parts.
High quality with LOW LOW tooling.
We MAKE GOOD PART sir.
Sometimes they do sometimes they do a really good job
