There won’t be an adjustment hole on a six-pack (2300 center carb?) divorced choke spring assembly. If it is adjustable, it will require removing the spring assembly from the manifold. Not all versions of that choke spring are designed to be adjustable, some are fixed.

Some related six-pack choke info here
