Clark c25c Error Codes, Running Rich

We have a Clark c25c, LPG, and it seems to be running extremely rich. Carbon monoxide output of our old Caterpillar forklift was 120ppm and the Clark pegged out our meter at 999+ppm. We recently serviced it with new plugs, wires, cap, rotor, and ignition coil.

I turned on the ignition, pumped the throttle x3 times, and the engine light flashed the following codes: 22, 77, 37, 41. Any help or pointing in the right direction is much appreciated! Thank you!
