If it is running really rich at dock the excess fuel in the cylinder is washing the oil off the cylinder wall and burning it From what I understand that can cause your rings and pistons to wear out quicker. since you just put a new carb on (if i understood what you wrote correctly) you need to tune your carb asap before you do damage to your motor then see if it still is acting up and stalling.
