The CCKW is a product of the 40's and most newcomers to these are products of the 60s and later that grew up with computerized throttle body ignition that starts in an instant, regardless of the skill of the owner. Starting these beasts takes a touch that only people who grew up in the days of the hand choke and Hand throttle can relate to. Your CCKW is just fine you have just got to learn how to start a vehicle all over again.
I get calls several times a year to check out antique cars and trucks that do not want to start. The owner will explaine how they "huffed and puffed", checked the tires, had it on level ground, had "mechanics" over, checked the wires, and a dozen other minor details, and remind that "it was just tuned" and they think the timing must be off or the points you installed are screwed up.
If the battery is up and the vehicle is still in tune, the problem vehicle is usually running within 30 seconds. Sometimes I have to go back for a repeat performance.
It is sort of a "man" thing to not want to accept that one can't start their vehicle.
Face it, we wouldn't have won WWII with untrained drivers from 2007.Each CCKW starts a bit different than the others, they all have their own starting personality, starting one is a matter of acquired skill and instinct.
It happens more often than than you think, just follow the posts on this and other MV sites. They litterally end up jacking up the radiator cap and putting a new truck under it.
Why do you think the Army had instructors, TM's and Training schools in WWII?

What do you think about the prime lever in the fuel pump?
