Alright, so I fully closed off the ‘to tank’ vapor line. My truck ran just fine and idled perfectly, where as the carb was bone dry and the truck was unable to start beforehand. My uncle informed me the previous owner had it closed off to begin with and that he actually reattached it to the canister. Do you think it’s still something to do with the carb? Someone else said something about a possible clog in the overfill limiter tube of the gas tank.
