I've scored what I hope is a good deal on a standby generator. I picked up this Generac with a transfer switch for $600.

It has 267 hours on the clock. The story is that it came from a firehouse and it aged out and was replaced. I was told it was set up for natural gas and I've had that hooked up from the house. I replaced the 11 year old battery (yikes!) and fired it up, but ... no love. I checked for spark at the plugs, and that's good. I was able to read this off of the first valve in line from the house.

We've (my electrician and I) determined that the solenoid is not working. Generac part # 043768A. Made of Unobtainium, NLA. He gave me another part # to look for, Y74521. Comes up as a general purpose solenoid. Would that work as a replacement? Better suggestions for a replacement?
I thank you in advance for your help and input. Dave

The 3/4" solenoid valve in the first picture?

I believe that is still manufactured. Just maybe not under the Generac part number.

There are many alternatives, as well.

I've gotten it up and running, but it's not generating any. How do I test the windings? Here's what I'm looking at re: the brushes.

What is the resistance from slip ring to slip ring? You may have to clean them up a bit as well.
