Generac PW Not Starting...

I have posted in the past about this PW(never again will I buy a generac product). Head is in, valves adjusted to specs, cleaned carb(but only bowl and sprayed inside and did not unscrew any internals), torqued the head bolts to 140in lbs(many thanks cheese) buttoned up, and this thingamagig won't start. I went to autozone and brought an ignition tester and hooked it up and apparently i'm getting spark(see youtube video). What DO I NEED TO GET THIS RUNNING??????? I'm short of giving myself a very painful haircut with my fingers.

Ok, I was able to start it, but does this idle seem normal? Here is a video.

No...that is not normal. The generator is hunting. It could be from a too lean condition at the carb.

Thanks Man. I did find a screw on the side of the carb(see photo) which i'm hoping is an adjustment screw. Is it? If yes, what is the procedure for adjusting the carb? Is it done while the machine is running?

The other photo is of the spring that is attached to the throttle. It seems a bit bent up. Can that also be an issue? I really appreciate and value everyones help.

Not knowing that unit I can't give you an exact answer but you could try turning that screw 1/4 turn counterclockwise and see if there is any change. Try a second 1/4 turn if no improvement.

Just make sure you count how many turns and which direction so you can get back to your starting position,

Yes....a bent up governor spring could also be an issue.

The problem is that generac sells some cheap chinese engines on their stuff now. They say they make their own engines and try to hide the fact that it's not US manufactured stuff, but it's not.

In the first pic you posted, just barely making it into the picture is a black plastic screw. This is the idle speed screw. Take it all the way out. Then, under where the screw was is a black plastic plug. Pull it up, or pry it up with a flathead screwdriver. It has a tiny hole in it right in the middle, plus a bigger one through the side. Stick a piece of wire through the holes, especially the tiny one in the center.
