Generator hard start

My rig has a Generac Guardian Quietpact 40G gen set.
It has been giving me a hard time. I found the carb was varnished, and the fuel solenoid was no good. I've since replaced the carburetor. Now the generator only starts if I hold the throttle closed. The choke appears to be cycling normal, and I have fuel.
It seems odd that I have to hold the throttle closed, to start. After it starts, if runs fine. I can also restart hot no problem.
I'm stumped now.

    sprays don,t do much more carbs, it goes right to the piston, t6ry sea foam in the fuel ,it,ll clean things up.

    I'll 2nd Seafoam but you may also have a bad/hardened float valve o-ring.
    Seems to be a common occurrence ever since ethanol has been added to gas.

    I've had this problem a couple of time on other small engines

    I tried the spray before I replaced the carburetor. I haven't added any to the fuel.
    I've also verified strong spark, and replaced the spark plug while I was at it.
