I agree with the carb adjustement. The factory has no idea where the auger is going to end up, so they cannot set the carb appropriately for the altitude, temp, etc that the auger will be used in. If you are pretty handy you can probably set the carb yourself, otherwise a good small engine shop will be able to do it for you. However since you brought up that maybe you might consider a different brand now, I would strongly consider an Eskimo. I went from a Jiffy to an Eskimo, and I can't see myself ever going back, they are one hell of an auger. Do a little research, but I don't think you are going to find many people that have anything bad to say about an Eskimo auger.
