fulton fire

i took a closer look at the carb and the butterfly is only open about1/2 way even when gas is wide open so im going to take off the carb and fix it . ty for the input

i am having a problem with my 45 model 45 when i hit the highway all is well until i go about 40 mph then all of a sudden it dies and the choke knob pulls out by itself. i have replaced all the fuel lines ,installed a new fuel pump, i even took off the fill tube cap thinking it was pulling a vacum in the tank due to poor ventalation. i was wondering if anybody has ran into this problem. i will be driving this truck to a state fire convention in 2 weeks where it will be used for the pumper races so any input will be great because i would like to drive it there instead of trailering it. thank you for and help.

trying to find owner's manual or book that will help with rebuilding this truck 1945 model 45 firetruck . thanks for all the help
