Is there a way to tell on the jet to see what number it is

It will be stamped into the jet itself.

Ok so the one that isn’t used has like 6.88 or 5.8? Stamper into it. So I guess the correct one is installed then

I don't think I would 'guess' at anything... These units also had a fuel setting in the controller that needed to be changed which I believe alters timing. Best to start simple and work your way out. You could get all the way to the end, completely stuck, and find out something simple like an improperly installed fuel jet caused all this hassle...

In the nexus controller do you know how to see if it’s right?

Go to the edit menu and scroll through until you see 'Fuel Selection'. I can't remember off the top of my head, but I don't think that's buried behind the dealer menu on the Nexus panels.

Tried that. Seems to be behind some password screen. Not even sure how to do that. Just want to verify it wasn’t changed to lp as I bought it used

I think you may be approaching the point where it is necessary for a Generac dealer to come out and have a look at the machine and see if they can determine what's going on...

Have you verified the proper NG jet is installed?

Ok. So I had my local dealer come out. They changed the plugs and air filter.

I confirmed the the nexus controller was set to NG. I’m going to dive into the jet tomorrow hopefully.

Still set to exercise on Sunday. Came home a over crank.

It’s currently 38 degrees. Here. This damn thing should start no problem.

I am going to replumb the gas line as it has a big loop and I feel that might be a problem too
