Big Chevy - I've got an original Rochester carb - I start the truck no problem, but after about 1 minute, gas starts spewing from the rear of the carb. I hate to admit it, but removing the carb is the extent of my carb knowledge - seems to me a rebuild is in order...Does that ring true to you? additionally, I've got some charging issues...go figure...thanks for asking - any input would be greatly appreciated - truth be told, I'm a novice...thanks again.
