For some reason, my truck won't stay fired unless gas is constantly applied to the carb. if i take the gas off after i start it up, it will die, it also dies when it put it into gear. I assume this has to do with either the idle, choke or carb. I think i just need to increase the amount of gas that goes into the carb when it is in idle. Please let me know if there is an easy way to make the adjustments needed to fix this. the more detail, the better. thanks for everyone's help.
