.... these old trucks can be cantankerous sometimes. To much choke and the carb is flooded with gas, not enough and it won't fire a lick! Since it hasn't ran in a long time I'd have a helper close by and very carefully pour just a little gas down the carb while trying to crank it. If it fires then you know your getting spark. If it fires but won't keep running then the likely hood is its not getting gas.
Lots of things can happen. Just keep us posted on what your doing, how its acting and the guys around here will have you running before long. Good luck, keep us posted.
