Kawasaki FH451V choke not closing

I have a Bobcat walk behind mower with the kawasaki fh451v. Towards the end of last season it was hard to start when it was cold. If I sprayed some gas in there it would fire up and be fine the rest of the day. Today I took it apart to check what it was and the choke is not closing at all. This mower has the choke and throttle on one throttle cable. I tried adjusting the control panel and I still can't figure out how to get it to close. I'm not sure if all the parts are there or if I am adjusting the right parts. I don't have an exact model number for the engine as the numbers are wore off of the sticker on the side of the engine. But I know it is a fh451v for sure. Any help is appreciated.

Adjust by sliding the throttle cable back and forth under the retainer clip, Moving the control panel raises/lowers high speed rpm's.....

Loosen the throttle cable clamp on the control panel then move the the throttle/choke lever to full choke. Move the cable so that the choke butterlly closes completely. Tighten the clamp screw.

No need to move the control panel unless you need to increase/decrease rpms.

Make sure your throttle cable is pulling the arm as far as it will go. Should hit on the cut out hole in the control panel.

After that, there is an adjustment screw on the back of the control panel that adjusts the choke. Its kinda a PITA to get to. And its tougher to see on the 451's because the air filters is in front of the control panel.

Kawasaki's combined system is a piece of crap IMO. Have had far less trouble with Briggs or Kohlers staying in adjustment. Glad the newer ones just went to a separate choke.
