the jb weld would not be a good idea. doesnt allow for further maintenance on the carb. there is a heli coil kit offered for this as this topic was covered not too long ago. maybe last winter if im correct. can get it at napa i beleive. i think it can be gotten from classic as well in their carb section but not positive. someone mentioned a big parts supplier having it but id try napa first. if necessary to find out size/ takie carb off or find out size of tubing into carb and take it there when you go.
